In this embodiment, as shown in FIG. 3, one end 9a of the rotating portion 9 is fixed near the upper part of the reciprocating means 7 (specifically, the upper part of the cylinder tube), and the other end 9b is described later. The arm 10 is fixed to a shaft portion 11 which is to be mounted. Specifically, the arm is formed in a trapezoidal shape without a bottom, and the arm is fixed by a nut after a reciprocating means 7 is inserted into a through hole provided in an upper side thereof. As described above, the support stability can be further improved by forming the rotating portion 9 as an integral body formed in a trapezoidal shape.

The other end 9b of the rotating portion 9 is fixed to a shaft portion 11, and the shaft portion 11 is rotatably supported by a bearing portion 12. That is, the support portion 10 of this embodiment is
