<P>PROBLEM TO BE SOLVED: To provide a dimmer capable of reducing deformation and damage of a pawl section and a pawl receiving section while preventing a gap in the direction orthogonal to the assembling direction of a cover and body. <P>SOLUTION: The dimmer has a box-shaped case, an operation knob arranged on the front face of the case, and a plurality of circuit elements housed in the case and constituting a dimming circuit in order to light-control a lighting load in response to operation of the operation knob. The case is provided with a front-side cover 3 and a rear-side body 4 which are assembled with connection pawls 3b and connection holes 4b. Recessed sections 3f and projected sections 4d, which are mutually connectable to regulate relative movements in the three directions among four orthogonal directions viewed from the frontward/backward direction in the state that the cover 3 and the body 4 are assembled, are arranged in the vicinities of respective both sides of the connection pawls 3b and the connection holes 4b for the cover 3 and the body 4. <P>COPYRIGHT: (C)2009,JPO&INPIT |
