In a state that the supporting member is supported by the bearing portion, the one end portion is inside the accommodation frame, and a distance between an end portion of the bearing portion in a rotational axis direction and an end portion of the helical blade closest to the bearing portion is larger than a distance between the end portion of the bearing portion and an end surface of the shaft portion.
