In a connection mechanism that connects a valve shaft to air cylinders, shake prevention mechanisms are disposed at facing portions at which outer side surfaces of side frames face inner side surfaces of housings of the air cylinders and/or facing portions at which inner side surfaces and of the side frames face left-hand and right-hand side surfaces of a center frame. The shake prevention mechanisms include a sliding member that is disposed on a sliding surface that is formed on one of two surfaces that face each other and on the other and a spring mechanism that presses the sliding member in a direction in which the sliding member comes into contact with the sliding surface.

A cylinder guide mechanism includes a floating bush, a holding part that holds the floating bush, and a linear guide. When a working fluid is supplied in a tube and a piston rod moves back and forth, the floating bush and a guide member of the linear guide move back and forth in the same direction. At this time, a slider of the linear guide is displaced relative to the guide member by retaining the same position. The slider is connected to the tube via an L-bracket.

Cylinder guide mechanism and cylinder with guide mechanism

A linear actuator. A guide block for constituting a guide mechanism includes a pair of ball circulation grooves formed in the lower surface of the guide block, the lower surface facing a cylinder body, and balls are mounted in the ball circulation groove. A pair of cover blocks are respectively mounted to the opposite end surfaces of the guide block, and the base section of a cover plate of a plate material is mounted to the lower part of the guide block to thereby retain the balls within the ball circulation groove. Hook sections provided to ends of the base section are engaged with the cover blocks to thereby integrally connect the cover blocks and the guide block.
