Vibration test device for driving simulator

An object of the present invention is to provide an actuator capable of reducing a shock in acceleration at the time of a turn caused by a load in a lateral direction orthogonal to an axis of the actuator even when the load is excessive while reducing manufacturing cost and manufacturing man-hours, and a tripod structure including the actuator. An actuator according to the present invention includes: a pipe; a ball screw used as a feed screw; a conversion nut used as a feed nut and screwed with the ball screw; a piston fixed integrally to the conversion nut and driven to expand and contract from a free end which is one end of the pipe; and a rolling bearing unit being provided on a tip of the free end of the pipe and including a plurality of roller followers holding the piston movably.

Actuator and tripod structure equipped therewith

An actuator includes a cylinder sandwiched between a fixing plate fixed to the other end surface of a supporting plate together with a servomotor and a bearing housing, a ball screw shaft having one end protruding into the cylinder through through holes of the fixing plate, a slide block screwed with one end of the ball screw shaft in the cylinder, a cylindrical-shaped piston coupled to an end of the slide block and reciprocatably located in the cylinder, linear motion bearing units located inside the bearing housing to movably support the piston, and linear motion bearing units located in the cylinder to movably support the slide block.
