固定したボールスプライン軸受を介して外筒に軸方向移
動のみ自在に支持したことを特徴とする電動シリンダ。A ball screw is inserted into the outer cylinder and rotated by the drive shaft, a hole nut moves in the axial direction of the ball screw as the ball screw rotates, and the proximal end is attached to the hole nut by the backward movement of the pole nut. In an electric cylinder consisting of a hollow output shaft rod that is drawn into the cylinder and pushed out from the tip of the outer cylinder by the forward movement of a ball nut, an appropriate number of axial splines are formed on the outer periphery of the output shaft rod. An electric cylinder characterized in that an output shaft rod is supported by the outer cylinder through a ball spline bearing fixed in the outer cylinder so as to be freely movable only in the axial direction.
