The locking body has a pair of elastically deformable locking pieces that are bent downward from both side edges of the horizontal base portion. Are formed so as to be able to spread apart from each other, and an insertion hole for inserting a mounting bolt is formed in the base portion so as to face between the opposite ends of the lower end edge of the locking piece. To prevent the elastic force of each locking piece from The lower end edge of each locking piece is locked to the thread of the mounting bolt by advancing it between the lower ends of the respective locking pieces, and the locking tool is pushed up along the mounting bolt and touches the instrument body. It is characterized in that the device body is supported by being brought into contact therewith.

As a second means, in addition to the first means, a spring piece is provided on the upper portion of the base portion of the locking body, and the spring piece is pushed up along the mounting bolt to push the spring piece. And then in this state, by rotating the locking body through the case, the lower edge of each locking piece is moved along the wall surface of the thread of the mounting bolt to raise the locking tool. The spring piece is displaced, and the spring piece is pressed against the instrument body against the elastic force by this upward displacement.

Further, as a third means, there is provided a mounting device for a lighting fixture, wherein a locking body provided in a lighting fixture main body is inserted into a mounting bolt protruding from the mounting base to attach the lighting fixture main body to the mounting base. The locking body has a pair of elastically deformable locking pieces that are bent downward from both side edges of a horizontal base portion, and the lower end edges of these locking pieces face each other so that they can expand. An insertion hole for inserting a mounting bolt is formed in the portion facing the lower end edge of the locking piece facing each other, and the mounting bolt is inserted into the insertion hole so that the mounting bolt resists the elastic force of each locking piece. Then, the lower end edges of the respective locking pieces are engaged with the threads of the mounting bolts by advancing between the lower ends of the respective locking pieces so as to support the instrument body.
