Abstract
A horizontal articulated robot includes a base, a first arm supported by the base to be pivotable in a horizontal direction, a second arm supported by the first arm to be pivotable in the horizontal direction, a shaft supported by the second arm to be linearly movable along a longitudinal axis in a vertical direction, and a stopper mounted to the shaft and limiting movement of the shaft within a movable range. The stopper includes a fixing section fixed to an outer circumferential surface of the shaft and protruding therefrom, and a shock absorbing section fixed to one of the fixing section and the second arm. The shock absorbing section is disposed in a position sandwiched by the fixing section and the second arm in the vertical direction, and is elastically compressed in the vertical direction when the shaft tries to move beyond the movable range.
