A product obtained by laminating a skin on the surface can be adopted.

  As shown in FIGS. 4 and 5, the bracket 1 is spaced in one direction P (that is, in the vehicle front-rear direction P when the bracket 1 is mounted on the ceiling member 2) so as to support the speaker device 3. A first support member 5 and a second support member 6 arranged side by side, and a first flexible portion 7 and a second flexible portion 8 connecting the first support member 5 and the second support member 6; Have. Each of the supports 5 and 6 and each of the flexible portions 7 and 8 are made of a resin (for example, a resin containing a fiber material such as a plant fiber, a glass fiber, and a carbon fiber) and are integrally formed. Each of the supports 5 and 6 is formed in an elongated shape in a direction orthogonal to the one direction P. Each of the flexible portions 7 and 8 is formed in a substantially V-shaped plate shape. The first flexible portion 7 connects one end of each of the supports 5 and 6 in the longitudinal direction, and the second flexible portion 8 connects each of the supports 5 and 6 to each other in the longitudinal direction. The ends are connected. Therefore, the bracket 1 is formed in a frame shape as a whole, and an opening 9 is formed in a central portion surrounded by the supports 5 and 6 and the flexible portions 7 and 8.

  Each of the first and second supports 5 and 6 is in contact with a surface of an outer peripheral edge of the opening 2 a of the ceiling member 2 to support the speaker device 3.
