PROBLEM TO BE SOLVED: To provide a luminaire constituted so that optical axis adjustment is not easily performed after completion of optical axis adjustment by closing a guide hole after completion of optical axis adjustment of an adjusted body, and having a closer fixed to a holding part. SOLUTION: An axis part 40 and a small protrusion 42 of a blocking body 4 is pressed into a guide hole 31. Then, the bottom face of an eaves part 44 of a head 41 and the top face of the small protrusion 42 abuts and sandwiches both of the top and bottom faces of a holding part 30 at a marginal rim of the guide hole 31, and the blocking body 4 is fixed to the holding part 30. As a result, after completion of optical axis adjustment, since the guide hole 31 is closed by the blocking body 4 fixed to the holding part 30, an adjust screw cannot be turned by inserting a tool into the guide hole 31, and therefore, optical axis adjustment is not easily performed after completion of optical axis adjustment. In particular, a top 43 of the head 41 of the blocking body 4 is made of a semi-spherical shape which is hardly gripped, and the eaves part 44 of the head 41 of the blocking body 4 is a circular collar shape which is hardly gripped, and therefore, stripping of the blocking body 4 is difficult. |
