摘要： Provided is a rack bush capable of reducing an effect on the feeling of a steering operation. A rack bush (1) comprises: a rack bush 1 housed in a cylindrical housing (4), which supports a load applied to a rack bar (5) while allowing movement of the rack bar (5) in the direction of the axis (O) and can be freely expanded and contracted in the radial direction; and elastic rings (3) mounted on the bush body (2). The bush body (2) has mounting grooves (28), which are formed in the circumferential direction on an outer peripheral surface (22) for mounting the elastic ring (3). An axis (P) of the mounting groove (28) are shifted from the axis (O) of the bush body (2). By this arrangement, there are formed an elastic ring protruding part (10), where the elastic rings (3) protrude greatly from the outer peripheral surface (22) of the bush body (2), and an elastic ring embedded part (11), where the elastic rings (3) are embedded in the outer peripheral surface (22) of the bush body (2).

摘要： The objective of the present invention is to reduce the impact of production variability in a radius of curvature of a rear surface of a rack bar, for example, while enlarging a region of contact with the rack bar. A concave surface (330) is used as a rack guide seat (32) sliding surface (33). In a YZ cross section perpendicular to an axial direction of a rack bar, the concave surface (330) includes: a pair of first arcuate surfaces (331A, 331B) which are disposed on a peripheral edge side (320) of the sliding surface (33), from two positions of contact TA, TB with a rack bar rear surface (22), the positions of contact TA, TB having line symmetry with respect to a straight Line O3 joining a center O of a rack bar (20) with a bottom portion center C of the sliding surface (33), and which have line symmetry with respect to the straight Line O3; and a pair of second arcuate surfaces (332A, 332B) which are disposed on a bottom portion side (321) of the sliding surface (33), from the positions of contact TA, TB, and which have line symmetry with respect to the straight Line O3. With regard to gaps to the rack bar rear surface (22) in positions separated by the same distance from the positions of contact TA, TB, the gaps from the first arcuate surfaces (331A, 331B) are greater than the gaps from the second arcuate surfaces (332A, 332b).

摘要： A more durable rotation transmitting member for a coupling directly connected to shafts has: drive-side rotation transmitting cushion to which an input shaft is directly connected; and a hub to which an output shaft is directly connected. Two parallel flat surfaces are formed on the outer periphery of the front end of the input shaft, and a shaft hole receives the front end of the input shaft and is formed in the rotation transmitting cushion. Surfaces of the inner wall of the shaft hole protrude toward the axis (O) to face input shaft front end flat surfaces. Each protruding surface comprises two flat sloped surfaces extending in the direction of the axis (O). When the input shaft starts to rotate, each front end flat of the front end comes into surface contact with one of the protruding surface sloped surfaces which faces the flat surface.

摘要： A slide bearing which can be manufactured at low cost is provided. The slide bearing (1) is provided with a cylindrical bearing main body (2) into which a shaft member is inserted, and an elastic ring (3) for urging the bearing main body (2) diametrically inward, the elastic ring (3) being mounted to the bearing main body (2). The bearing main body (2) has a sliding surface (21) which slides against the outer peripheral surface of the inserted shaft member, a plurality of first slits (25) running along the direction of an axis O from one end surface (23) toward another end surface (24), a plurality of second slits (26) running along the direction of the axis O from the other end surface (24) toward the one end surface (23), a plurality of first elastic ring interlocking parts (27) protruding diametrically outward at one end part (220) of the outer peripheral surface (22), and a plurality of second elastic ring interlocking parts (28) protruding diametrically outward at another end part (221) of the outer peripheral surface (22). The first elastic ring interlocking parts (27) and the second elastic ring interlocking parts (28) are positioned so as not to overlap each other seen in an imaginary plane P perpendicular to the axis O.
