Abstract
A working machine may include a pipe including: an outer pipe; an inner pipe inserted in the outer pipe; a pipe holder fixed to the outer pipe; and a stopper disposed inside the outer pipe. The pipe holder includes a wall part. The inner pipe includes a fixing hole having a longitudinal direction in a circumferential direction of an outer circumferential surface of the inner pipe. A rear surface of the fixing hole has a shape extending along a plane orthogonal to a front-rear direction. The stopper includes: an abutting part that abuts the wall part from behind when the inner pipe extends to a maximum length relative to the outer pipe; and a protruding part configured to fit in the fixing hole of the inner pipe. A rear surface of the protruding part has a shape extending along a plane parallel to the rear surface of the fixing hole.
