SOLUTION: A first rib 11 is provided along a joint surface of an upper case 10 around the periphery of either the upper case 10 or a lower case 20. Plural engaging pawls 13 to mutually hold and fix the upper case 11 and the lower case 20 are provided on either the upper case 10 or the lower case 20. A second rib 21 is provided at a notch of the case side face on which the first rib 11 is not provided. In addition, third ribs 12, 22 that abut in the direction of the periphery of the upper case 10 and the lower case 20 engaged are provided at the engaging pawls 13 and the second rib 21 to prevent shift of the upper case 10 and the lower case 20 in the thrust direction.</p> |
