<p>PURPOSE:To reduce the labor required in assembling work by forming positioning protruding parts provided with guiding inclined surfaces approaching toward the leading ends thereof to the surface and rear of a holding frame and forming the recessed parts provided with the inclined surfaces to be guides coming into contact with the guiding inclined surfaces in exterior panels. CONSTITUTION:A printed circuit board 12 is received in the receiving recessed part 13 of a holding frame 14 and, when exterior panels 17, 18 are mounted on the surface and rear 14a, 14b of the holding frame 14, the inclined surfaces 4a, 5a to be guided of the positioning recessed parts 4, 5 formed to the exterior panels 17, 18 are guided along the guiding inclined surfaces 2a, 3a of the positioning protruding parts 2, 3 formed to the surface and rear 14a, 14b of the holding frame 14. When the exterior panels 17, 18 are mounted, the inclined surfaces 4a, 5a to be guided come into contact with the guiding inclined surfaces 2a, 3a in a corresponding state and positioned in such a state that the outer peripheral end parts 17a, 18a of the exterior panels 17, 18 coincide along the planar direction of both panels while subjected to positioning along the planar direction.</p> |
