PROBLEM TO BE SOLVED: To solve the problem of flawing a front face of a cap by contact with an engaging member, when stored in a bezel by flipping up the cap against bias force of a plate spring, by pressing the engaging member to the front face of the cap.SOLUTION: The cap is held in a position for covering an opening 40F of the bezel by engagement of the bezel 40, an engaging hole 46 provided in the cap 50 and an engaging projection 54. A straight line-shaped guide groove 42 extending in the longitudinal direction is provided on left-right side surfaces of the bezel, and a hinge pin 52 is provided in the cap, and is slidably fitted in the guide groove. A regulation pin 44 abuts on a back face of the cap for covering an opening of the bezel, and projects to the inside from the left-right side surfaces of the bezel so that rocking of the cap can be regulated, and when pressing force for sliding the hinge pin by pushing in the guide groove is added to the cap, the back face of the cap slidingly contacts with the regulation pin, and the cap rocks with the hinge pin as the rocking center, and is stored in the bezel by being flipped up. |
