    摘要： Prior to engaging a male screw formed on the outer circumference of a second member with a female screw formed on the inner circumference of a hole in a first member, protruding parts which protrude outward in the radial direction and are positioned at one end side of the male screw in the axial direction are formed in a plurality of regions which are separated from each other in the circumferential direction on the outer circumference of the second member on which the male screw is formed. The male screw is then engaged with the female screw from the other end side of the male screw in the axial direction. The torque required to rotate the male screw engaged with the female screw in the loosening direction is set so as to be greater in a state where the protruding parts are interposed between the male screw and the female screw than in a state where the protruding parts are not so interposed.

    摘要： With a rack-and-pinion mechanism, an impact force is absorbed and reduction in assembling performance is suppressed. An annular fitting groove (51) that extends in the circumferential direction of a rack guide (41) is formed in an outer peripheral face (41a) of the rack guide (41), and an O-ring (52) is fitted in the fitting groove (51) in a state in which the axial movement of the O-ring (52) is restricted. A communication groove (61) that provides communication between an internal space (55), defined by the fitting groove (51) and the O-ring (52), and the outside of the rack guide (41) is formed in the rack guide (41).
