PURPOSE:To facilitate a mounting operation of a body by inserting the body into an opening, and bending a mounting member at a part protruding from a through hole of a flange down in a state that an engaging part of an upper part of a mounting part is engaged with an upper surface of a wood frame. CONSTITUTION:When a mounting member 24 is lifted in a state that a body 14 is lifted until a flange l5 is brought into contact with a lower surface of an opening 12 to pass the part 25 through a wood frame 13, the part 25 is reset to an original state by its own elastic strength, and engaged with an upper surface of the frame 13. When a hand grip 24a of the member 24 is held by a hand and strongly pulled down in this state, the part 25 is elastically deformed in a direction of an arrow B, and hence a part of the member 24 protruding from a through hole 23 is bent acutely in an inward of the body 14. Thus, since the body 14 can be mounted in the frame 13, the body 14 can be easily mounted in a short time. |
