In g-transfer, the user can grasp the operating member by moving the hand a short distance along the axis of the end section of the no-endor ζ-, with the thumb and index finger arched. Even in this state, which will be described later, the palm and remaining fingers remain close to the end section of the grip handle or the member fixed thereto, so that even if an un-lance occurs, the hand remains on the handle. Alternatively, the member fixed thereto can be easily grasped. That is, the configuration of the present invention provides significant human-biological advantages.
