Further, the rib for holding the operation board 70 inside the operation board mounting portion 54 may have a structure that temporarily holds the operation board 70. That is, since the ribs can be formed thinner than the thickness of the portion constituting the design surface, even if the ribs are integrally molded together with the pipe portion 50 constituting the design surface, the sink marks during resin molding affect the design surface. Such phenomena can be suppressed.

Further, since the rear end holding rib 55d for temporarily fixing the operation board 70 is a portion protruding upward from the bottom of the operation board mounting portion 54, the thickness of the pipe portion 50 is increased in order to increase the strength. By making the structure the same or thicker, even if a sink mark occurs during resin molding, the sink mark is located on the lower surface of the pipe portion 50, so that the influence on the design surface can be reduced.
In the present embodiment, the operation board 70 is temporarily fixed by the rear end holding rib 55d so as not to come off upward, but the front end holding rib 55c can be elastically deformed like the rear end holding rib 55d. It may be configured so that the operation board 70 can be temporarily held.
