<p>PURPOSE:To ease restraint on positioning, with no additional parts and work processes, for sure fixing of a main body to a mounting plate by making the axis of a supporting point of an engagement part, with elasticity, bent toward the mounting side for the main body approximately vertical to the end part of main body. CONSTITUTION:Relating to a pre-assembled ballast main body 1 consisting of an iron core, coil, etc., a claw-like projection 2 is provided on the mounting side of a capacitor mounting plate 3. Meanwhile, on the mounting plate 3, a tongue-like piece 4 that is engaged with the mounting surface for the main body 1 and the projection 2, and an > shaped engagement part 5, having elasticity, bent toward the mounting side for the main body, with the intension that an axis 8 of a supporting point be nearly vertical to an end part 9 of the main body 1, are provided. Thus, as elasticity of the engagement part is utilized, the pre-assembled ballast main body and a capacitor mounting part bracket are mounted easily with no such parts as screws, and further, the mounting plate can be fixed to the main body with sure.</p> |
