PROBLEM TO BE SOLVED: To enhance the braking strength of a flexible piece by adding a deforming function to a wall surface where the flexible piece having repulsive force is formed so as to distribute stress when this flexible piece is bent- deformed at the time of attaching/detaching, etc., a cosmetic tray. SOLUTION: The first engaging projection 28 which can be engaged with the engaging groove 24a of a cosmetic tray 24 is formed on the first inner surface 20a of a cosmetic tray housing part 20. Plural pawls 30 respectively forming a vertical slit 30a extended in a vertical direction on both sides and respectively making its lower end a free end, and the second engaging projections 32 which can be engaged with the groove 24a are formed on the inner surface of their lower end part. The second inner surface 20b between the pawls 30 is made a flexible holding wall 34 with a spring force larger than that of the pawl 30 by making its lower end a free end, and a projecting part 36 is formed on the inner surface of this by a projecting quantity smaller than that of the projections 32. A horizontal slit 38 is formed at the upper end part of the surface 20b over the whole width of the forming area of the wall 34 and the pawls 30.
