<p>To make it possible to downsize a device by reducing an occupied space on a chassis occupied by a holding mechanism of a guide shaft as much as possible. A support part 10 is constructed by integrally molding guide walls 12A, 12B which restrict movement of a guide shaft 4 in a radial direction, a stopper part 13 which restricts movement of the guide shaft in a thrust direction and a hook part 14 which restricts slipping-off of the guide shaft 4. A coil spring 21 is provided at a position opposed to the hook part 14 disposed between the guide walls 12A and 12B and the stopper part 13. Thereby, the holding mechanism 25 of the guide shaft 4 including the support part 10 and the coil spring 21 is organized to be compact, and the occupied space of the holding mechanism 25 in a chassis 1 is reduced.</p> |
