Since the tips of the elastic pieces a, a are wider than the inner peripheral diameter of the hole T1, the elastic piece a, by hand when the main body part b is inserted into the hole T1 formed in the ceiling T. It is necessary to simultaneously bend the tip ends of the respective a toward the main body b side against the elastic force of the elastic piece a, and insert them in that state. Further, since the main body portion b is attached to the ceiling T by the elastic force of the elastic piece a, a considerable force is required to bend inward against the elastic force of the elastic piece a by hand, which is very difficult. There is a problem that it requires a great deal of labor and the installation work is difficult. In particular, when the number of the elastic pieces a becomes three or more, it is difficult to simultaneously bend the respective elastic pieces a inward by hand. Further, after the lighting device is mounted in the hole T1 in the ceiling T, if the weight of the entire lighting fixture is heavy, the weight of the lighting device causes the elastic member a to entirely resist the elastic force of the elastic piece a. There is a risk of slipping the peripheral wall T2. When such a slip occurs, the whole falls from the ceiling. In this case, it is conceivable to increase the elastic force of the elastic piece a, but if the elastic force is increased, it is more difficult to manually bend the elastic piece a inward against the elastic force of the elastic piece a and insert it into the hole T1. Become.
