To easily position a fitting pin to a plurality of opened length adjusting holes at the time of adjusting the length of a stick.

In the stick whose entire length can be freely adjusted to be extended or contracted in a plurality of stages by bringing inner and outer cylinders into slide contact with each other, a plurality of the length adjusting holes are perforated at a fixed interval in a length direction at the connection part of the outer cylinder and the fitting pin fittable into one of the adjusting holes is projected and energized at all times so as to freely appear on an inner cylinder side face outer part by a spring mechanism inside the connection part of the inner cylinder. Also, on the outer peripheral surface of the inner cylinder corresponding to the appearing center position of the fitting pin, a position display line from one side of the fitting pin to the opposite side is performed. Thus, at the time of adjusting the length, through a desired length adjusting hole, the fitting pin is easily guided and fitted into the adjusting hole, and safety and operability are greatly improved.
