摘要： Provided is a ratchet wrench for greatly decreasing the amount of wear at sliding-contact surfaces between a shank and a member which is in contact with the shank. A shank (32) as a rotating member is brought into contact with a friction member (70) formed of a sintered copper alloy, but is kept out of contact with an annular holding portion (20b). By contact of the shank (32) with the friction member (70) formed of a sintered copper alloy, the amount of wear of a sliding-contact surface of the shank (32) with the friction member (70) and that of a sliding-contact surface of the friction member (70) with the shank (32) become extremely smaller than in the prior art. Consequently, it is possible to prevent a lowering of friction of the shank (32) and perform a tightening or loosening work for bolts, etc. stably over a long period.
摘要翻译：提供一种棘轮扳手，用于大大减少柄与与柄接触的构件之间的滑动接触表面的磨损量。作为旋转构件的柄（32）与由铜烧结合金构成的摩擦构件（70）接触，但与环形保持部（20b）保持脱离接触。通过柄（32）与由烧结铜合金形成的摩擦构件（70）的接触，柄（32）与摩擦构件（70）的滑动接触表面的磨损量和滑动摩擦构件（70）与柄（32）的接触表面变得比现有技术中显着地小。因此，可以防止柄部（32）的摩擦力的降低，并且长时间稳定地执行螺栓等的紧固或松动作业。

摘要： A middle electrical connector includes a plurality of terminals disposed on a terminal arrangement plate. A housing holds the terminal arrangement plate. The terminal arrangement plate has retaining grooves to hold the terminals at a plurality of positions. The retaining grooves includes a front retaining groove and a back retaining groove having at least one of a shape or a size different with each other. The front retaining groove holds a front retained portion of the terminal on a front portion side. The rear retaining groove holds a rear retained portion of the terminal on a rear portion side. When the terminal is inserted, the front retained portion is allowed to pass through the rear retaining groove.

摘要： In a ratchet wrench, a frictional force generation mechanism including a first guide bush and a disc spring is attached to a shank with a locking pin to form a shank assembly. Spring force of the disc spring acts only on the inside of the shank assembly. The shank assembly is inserted from a central space of a first annular hold portion toward a second annular hold portion, and the shank is held by an inner wall of the second annular hold portion. In the back side on which the shank assembly is inserted, the drop-out of the shank assembly from the central space side of the first annular hold portion is prevented by a snap ring attached to a groove of the first annular hold portion. With this arrangement, constant friction is applied to the shank.
