PURPOSE:To improve assembling efficiency as well as appearance with the number of components reduced by a method wherein an upper coupling portion of a light component storing case is coupled by screws and a lower coupling portion is coupled to both ends of a lower chassis member by engaging an engaging protrusion and an engaging recess with each other. CONSTITUTION:An apparatus is formed in a rectangular frame of an upper chassis member 11, a lower chassis member and a pair of right and left light component storing cases. Both light component storing cases are provided with coupling portions to be coupled with both ends of the upper chassis member 11 and the lower chassis member, respectively. The upper coupling portions of both light component storing cases are coupled to both ends of the lower chassis member with engaging protrusion 17 and an engaging recess engaged with each other. This realizes an apparatus whose number of components is small, having assembling efficiency and appearance improved with no screwed portions at a lower portion which is visible in an assembled state. |
