Abstract:
PURPOSE:To prevent a trouble from occurring due to the deformation of a shutter by providing a groove to guide a projection on the end face of a shell, and abutting the projection on the terminating plane of the groove. CONSTITUTION:The shutter 2 is formed in U-shape consisting of a front plate 21, a rear plate 22, and an end face plate 23 which connects them, and the projection 24 facing inside provided on the front plate 21 is fitted in the groove 13 of the shell 1, and also, the projection 4 facing inside provided on the end face plate 23 is fitted in the groove 5 of the end face of the shell 1. Also, a spring 3 which presses the shutter is mounted by connecting one terminal of it to the projection 4, and the other terminal to the shell 1. Then, by constituting the device so that the projection 4 can abutted on the terminal plane 51 of the groove 5 when the shutter 2 is set at a closed position, the shutter 2 can be surely prevented from coming off a recessed part 12. Thereby, it is not feared that the shutter 2 rides across the recessed part, and no trouble occurs due to the deformation of the shutter 2.
