摘要:
According to the present invention, a resin composition preferable for molding a sealing member superior in abrasion resistance at a high temperature, mountability on an axis and seal groove with deformation, and sealability can be provided. The resin composition of the present invention contains (b) 1 part by weight - 7 parts by weight of a powder of a compound having a layer crystal structure, and (c) 8 parts by weight - 27 parts by weight of a resin powder, per (a) 100 parts by weight of polyether sulfone.
摘要:
A shaft seal in which a seal element (3) and a gasket (10) as held members are held between an outer case (7) and an inner case (6), and, a protruding portion (5) to locally increase holding pressure on the seal element (3) is disposed on a pressing face (4) for held member of the inner case (6).
摘要:
A rotation shaft seal having a seal element (10) of resin and an outer case (4) of metal in which an inner brim portion (4B) of the outer case (4) is extended in a radial inner direction (R 1 ) to make an inner peripheral end face (20) of the inner brim portion (4B) proximate to a rotation shaft (3) to form a grease well (25) between a back face (10A) of the seal element (10), of which longitudinal cross section is L-shaped or J-shaped, and the inner brim portion (4B).

An exhaust system includes: an exhaust pressure controller interposed in an exhaust passage and including: a pipe body including a side peripheral wall in which at least one port is formed; and a gas introduction wall for introducing an exhaust gas flowing from an upstream side of the pipe body so that the exhaust gas flows downstream without coming into direct contact with the port and vicinity thereof, one face of the gas introduction wall forming a pressure control path together with an inner face of the side peripheral wall while another face of the gas introduction wall forming an exhaust gas path along which the exhaust gas flows. The port communicates with the pressure control path, and the pressure control path communicates with the exhaust gas path at part downstream of the port.

A pivoting lever that is reliably locked. Tongue-like movable pieces (16) cut out in a squared U-shape are formed on both side faces of a cover member (12), and locking claws (17) are formed at intermediate parts of the movable piece (16). A pivoting lever (14) is pivotally supported on the support pin (15) of the cover member (12). Circular arc-shaped cam grooves (22) are formed in a lever body part (19), and locking holes (23) engaging with the locking claws (17) are also formed in the lever body part (19). When a mating housing is pressed into a housing (10) and the pivoting lever (14) is pivoted, the cam grooves (22) drive a driven pin and pull the mating housing toward the housing. In this process, the pivoting lever (14) is made to be in contact with the locking claws (17), pivots the locking claws (17) while pushing them down. When the housings are joined to each other, the locking claws (17) are returned to the original positions and fitted into the locking holes (23), setting the pivoting lever to a locked state in which further rotation and reverse rotation of the pivoting lever (14) are disabled.

Provided is a harness connection member having a cover member. In fitting a cover member (5) to a holder (1), a split slit (5a) is opened with use of a slit (5b), and wires (3) are inserted into the holder. Thereafter, the cover member (5) is moved to the holder (1), then moved over one projected annular part (1d) of the holder (1), and fitted into the projected ring parts (1d). A concaved strip part (5c) is fitted to a convexed strip part (1e) to complete the installation, whereby the cover member (5) can not be moved relative to the holder (1) in both of longitudinal and circumferential directions.
