EAGLE INDUSTRY CO., LTD.

There is provided a sliding component that allows easy introduction-in or out of a fluid between a groove and a communicating space. In a sliding component in which a pair of sliding rings rotate relative to each other and which partitions a sealed fluid side space and a leakage side space off from each other, a groove opening to one of the spaces is provided on a sliding surface of the sliding ring, and an inclined surface 6 that faces a fluid space formed between the groove of the sliding ring and the sliding ring and that is expanded toward one of the spaces is provided at an edge portion of at least one of the sliding rings on the side of the groove.

A pressure applying device includes a base body and a movable body that is driven forward and backward relative to the base body to apply pressure to an object to be acted upon, and the pressure applying device further includes an elastic body disposed between a front end surface of the movable body and a pressure applied surface of the object to be acted upon.

An electronic device includes a housing and a battery holder configured for holding a battery and removably inserted into the housing. A positive terminal and a negative terminal on the side of the battery holder are arranged side by side and a positive terminal and a negative terminal on the side of the housing are arranged side by side. The housing and the battery holder are provided with either a recessed groove extending in an insertion direction in which the battery holder is inserted into the housing or a protrusion extending in the insertion direction, and the recessed groove and the protrusion constitute a guide portion.

Provided are sliding components capable of obtaining a stable low-friction effect under a wide range of conditions of use. A sliding component has a relatively sliding surface. A base material of one of the sliding components is coated with a graphite film, and the sliding surface of the other of the sliding components is made of the graphite film.

In an exemplary embodiment of a sliding component, a sliding face S is provided with a first fluid-side negative pressure generation mechanism 12 including a first negative pressure generation groove 13 , and is provided with a second fluid-side negative pressure generation mechanism 14 including second negative pressure generation grooves 15 located on the second-fluid side of the first fluid-side negative pressure generation mechanism 12 , and is further provided with a dynamic pressure generation mechanism 10 including dynamic pressure generation grooves 11 on at least one of the first-fluid side and the second-fluid side of the first fluid-side negative pressure generation mechanism 12 and the second fluid-side negative pressure generation mechanism 14 , and the first negative pressure generation groove 13 is isolated from the second-fluid side by a land R, and the second negative pressure generation grooves 15 are isolated from the first-fluid side by a land R.

There is provided a sliding component disposed at a relative rotational location of a rotating machine to slide relative to another sliding component. The sliding component has a sliding surface provided with a fluid inlet groove communicating with at least one of a sealed fluid side space and a leakage side space and a dynamic pressure generation groove communicating with the fluid inlet groove and extending in a circumferential direction. Both side edges and a terminating end edge of the dynamic pressure generation groove are curvedly continuous with each other in a plan view.

A sliding surface of a first sliding component and a sliding surface of a second sliding component slide against each other in an intersecting manner such that first positive pressure generation grooves and second positive pressure generation grooves at least partially overlap each other. The first positive pressure generation grooves include at least one groove that differs in a position of a terminating end portion from other grooves. The one groove includes a terminating end portion located closer to a sealed fluid space side than a terminating end portions of the other grooves and terminating end portions of the second positive pressure generation grooves.

A pair of sliding members sliding relative to each other at sliding faces (S) is configured such that at least one of the sliding faces (S) includes a negative pressure generation mechanism ( 21 ) separated from a leakage side by a leakage-side land portion (R 2 ) and a land portion ( 26 ) arranged in the negative pressure generation mechanism ( 21 ). In the compact sliding members, sliding torque can be reduced and a sealing function can be maintained.

There is provided a restriction component with good slidability. A restriction component is provided on a back surface of a movable scroll that slides relative to a fixed scroll while rotating eccentrically, and restricts a rotation of the movable scroll while allowing the eccentric rotation of the movable scroll, and the restriction component is provided with a dynamic pressure generation groove configured for generating a dynamic pressure on the back surface of the movable scroll.

There is provided a sliding component capable of effectively retaining a fine wear product in a recessed strip portion. In a sliding component that is disposed at a location of relative rotation of a rotating machine and that slides relative to a counterpart sliding member, a recessed strip portion is formed on a sliding surface of the sliding component, and the recessed strip portion is provided with a step having a difference in height, which traps a wear product.
