摘要： A sliding mechanism comprises a sleeve member, two balls in the sleeve member, and an elastic member biased between the balls for urging each ball to project above either opening of the sleeve member. When the sliding mechanism is mounted on a second member, a reduction of friction and a permanent contact between the first and second members are effected because the second member is slidable with respect to a first member with balls being in elastic contact with the first member. This may reduce friction and maintain a permanent contact when first and second members are relatively moving.

摘要： A linear bearing is provided which can allow a shaft to relatively reciprocally move with respect to an outer race in the axial direction, and also to rotate in the circumferential direction. In the linear bearing of the invention, an outer race supports a shaft via balls which are retained by a retainer. A push ring is fitted to the outer race so as to be reciprocable in the axial direction. Three coil springs which are arranged at the intervals of 120° in the circumferential direction are contractedly interposed between a lid fixed to the outer race and the push ring, so as to press the push ring toward the retainer. Spring pins which protrude in the axial direction are fixed to the lid. Tip ends of the spring pins are reciprocally fitted into holes formed in the push ring, thereby preventing the push ring from rotating.
