摘要： A spring or springs are provided between driving-side members that operate together with an output shaft of a stepping motor, and driven-side members that operate together with a jaw member. Thereby, when the jaw members performs opening motion, the driving-side members and the driven-side member directly engage with each other, thereby allowing a driving force to be transmitted directly from the output shaft to the jaw members. When the jaw members performs workpiece-holding operation, the driving-side members and the driven-side member engage each other via the spring or springs, thereby allowing the driving force to be elastically transmitted from the output shaft to the jaw members via the spring or the springs. In this configuration, when the workpiece-holding operation is performed by the jaw members, the stepping motor is controlled so as to over-rotate in a buffered manner.

摘要： A linear actuator includes a guide mechanism and a retainer. On a guide block of the guide mechanism, a pair of ball-circulating grooves is formed on the lower surface that faces a cylinder body. Multiple balls are loaded in the ball-circulating grooves. Paired cover blocks are respectively mounted on the two ends of the guide block. The retainer has the form of paired ball clips, which are formed as arms to engage with the cover blocks when the clips are inserted in the ball-circulating grooves to hold the balls. Paired cover plates are respectively mounted on the end faces of the cover blocks, and arm-shaped cover clips are mounted so as to hold the cover plates. The cover plates, the cover blocks, and the guide block are thereby integrally linked.

摘要： A linear actuator includes a cylinder main body. With respect to the cylinder main body, a slide table is disposed for reciprocal displacement through a guide mechanism, which is disposed on the cylinder main body. A stopper mechanism having a stopper bolt is disposed on one end of the slide table centrally in a widthwise direction perpendicular to the longitudinal direction of the slide table. In addition, when the slide table is displaced along the cylinder main body, an end of the stopper bolt comes into abutment with an end of a cover of the guide mechanism, whereupon the slide table becomes engaged therewith and movement of the slide table is stopped.
