向に回転して厚肉部6の外側突部28が収容部25の内
面に圧着して主軸1と丸鋸3を一体に結合する。Assuming that the center of gravity of the member 11 is G in Fig. 5 (■), when the member 11 rotates at high speed together with the main shaft 1, the corner 34 of the member 11 becomes a fulcrum due to centrifugal force, and moves in the direction of the arrow in Fig. 5 (■). As it rotates, the outer protrusion 28 of the thick portion 6 presses against the inner surface of the housing portion 25, thereby joining the main shaft 1 and the circular saw 3 together.

9 are in contact. In the case of this embodiment, while the main shaft 1 is stopped, the movable coupling member 11 is rounded because the lower surface (including the corner 34) of the member is in contact with the outer peripheral surface of the main shaft 1 due to the weight of the member. Moving saw 3 becomes heavy.
