A linear motion mechanism includes: a shaft extending along a prescribed axis; a structural member provided with a cavity through which the shaft extends; and a spline nut and a ball screw nut that support the shaft so as to be rotatable about the axis and so as to be movable in a direction of the axis, respectively, with respect to the structural member. The spline nut and the ball screw nut are detachably attached to the structural member from both sides sandwiching the structural member via attachment flanges provided thereon. At least one of the spline nut and the ball screw nut is fixed to, inside the cavity, a power transmission member having an outer diameter larger than an outer diameter of one of the attachment flanges provided thereon and is attached to the structural member via an adapter having a larger outer diameter than the power transmission member.

Linear motion mechanism and SCARA robot

The present invention provides an unmanned transfer robot system including: an unmanned transfer vehicle capable of traveling on a road surface between a plurality of work stations; a robot that is mounted on the unmanned transfer vehicle; a sensor that is mounted on the robot and that detects a condition of the road surface; and a control unit that controls the robot and the unmanned transfer vehicle. Within an operation range of the robot, the sensor is disposed at a position where the sensor can detect a condition of the road surface in the periphery of the unmanned transfer vehicle, and the control unit controls the unmanned transfer vehicle on the basis of the condition of the road surface acquired by the sensor.
