Claims

[Scope of Claim for Utility Model Registration] (1) An outer cylinder with an uneven part formed in the axial direction on the inner circumferential surface of a cylindrical member having a C-shaped cross section, and with the protruding part as a raceway surface; A slit slightly narrower than the ball is formed on the outer circumferential surface of the fitted outer cylinder corresponding to the raceway surface of the outer cylinder, and a direction change groove and a return groove are formed in the recess of the outer cylinder in continuation with this slit to allow endless circulation of the ball. In a linear bushing that consists of a retainer with a passage and a number of balls inserted into the endless circulation passage of the retainer, the retainer inserted into the outer cylinder has a circumference formed at both axial ends of the outer cylinder. The axial position is determined by the C-ring-shaped side plates that fit into the grooves, and bent parts bent inward are formed on both end surfaces of the side plates, and at least the bent parts are held. An open type linear bushing characterized by pressing and contacting the container to spread it out. (2) The bent portion of the side plate is narrower than other portions, and presses and contacts only the retainer, and a portion of the circumferential groove of the outer cylinder has a continuous concave notch. Claims of the utility model registration, characterized in that the recessed part and the projection part formed at the corresponding position of the side plate fit together to position the cage in the circumferential direction. Linear bushing as described in item 1 above.
