摘要：
A speaker device includes a resin frame and a resin grille mounted thereto. In the resin frame and the resin grille, engaging claws that engage with each other are formed, respectively. An inclined surface is formed on at least one of the engaging claws of the resin frame and the resin grille, and the other engaging claw engages with the one engaging claw on the inclined surface. When environmental temperature falls, the resin frame and the resin grille contract in the vertical and horizontal directions, and, when the temperature rises, the resin frame and the resin grille expand in the vertical and horizontal directions. However, even when such temperature changes occur, the engaging claw of the resin frame constantly engages with the inclined surface of the resin grille. Therefore, no backlash occurs between the engaging claw of the resin frame and the engaging claw of the resin grille.
