A portion of the key memberis fitted into a notched portionprovided along a direction crossing an axial direction of one end side the stopper shaft portion. The other part of the key memberprotruding from the stopper shaft portionis fixed to the one of the caband the revolving frame. Even if the key memberis disconnected from the cabor the revolving frame, the coming-off prevention devicecan be prevented from falling off, without the stopper shaft portioncoming off the through-hole, because a portion of the key memberis fitted into the notched portionof the stopper shaft portion
