パイプなどの伸縮装置。 An outer cylinder, an inner cylinder slidably inserted into the outer cylinder, a shaft inserted into the inner cylinder so that it can be taken in and out, a ball pusher attached to the shaft, and a part Two or more balls that protrude inside the inner cylinder and press against the outer circumferential surface of the ball pushing part, and the other part protrudes outside the inner cylinder and press against the inner circumferential surface of the outer cylinder, and the shaft is placed below the inner cylinder. It is composed of a spring that presses the ball against the inner circumferential surface of the outer cylinder by the ball pushing part.When the ball is pressed against the inner circumferential surface of the outer cylinder by the ball pushing part, the inner cylinder is fixed to the outer cylinder, and the shaft An expansion/contraction device such as a pipe that is designed so that when the ball is pulled out of the inner cylinder, the pressure on the ball by the ball pusher is released and the ball can be pulled out of the outer cylinder.
