[Conventional technology]

In conventional recessed lighting fixtures, as shown in FIGS. 8 and 9, the fixture B is A leaf spring 50 bent into a box shape is screwed into a male screw 51 of the leaf spring 50. a wing nut 52, and a cylindrical side wall 53 of the lighting fixture body A. , a slit 54 that guides the male screw 51 of the leaf spring 50 so as to be movable in the vertical direction; A type that communicates with a mounting opening 55 for a leaf spring having a width larger than the width of the slit 54. At the same time, the leaf spring 50 has a cylindrical side when the wing nut 52 is tightened. A posture-maintaining flange 50a that comes into contact with the inner surface of the wall 53 and serves as a receiving part for operation reaction force is connected. It has been set up. Before installing the lighting fixture body A into the embedding hole H of the fixed wall W, , if the fixing tool B is tightened and fixed in the retaining position of the slit 54, the corresponding Do not press and operate the lighting fixture body A while elastically deforming the leaf spring 50 of the fixture B. The push-in operation requires a lot of effort, and the leaf spring 50 may damage the periphery of the embedding hole H in the fixed wall W. Therefore, in reality, after inserting the lighting fixture body A into the embedding hole H, The plate spring 50 will be attached to the light fixture main body A, but in this case, the male plate spring 50 Loosely screw the wing nut 52 onto the screw 51 in advance, and then insert it into the embedding hole H. While holding the inserted lighting fixture body A with one hand, grasp the wing nut 52 with the other hand. Then, insert the leaf spring 50 from inside the cylindrical side wall 53 to the outside through the mounting hole 55. , the leaf spring 50 is moved along the slit 54 to the locking position. First, it is necessary to tighten the wing nut 52. As a result, such complicated operations can be carried out in a narrow space within the cylindrical side wall 53 of the lighting fixture body A. Since it must be done with one hand in the space, it takes a lot of effort to install the lighting fixture body A. It took a lot of effort. In addition, as a method to improve such problems in the installation surface of the lighting fixture body A, As shown in FIG. 10, the fixture B is shaped into the cylindrical side wall 53 of the lighting fixture body A Almost U-shaped in plan view, movable inward and outward directions through the slit 54 formed. Due to the contact between the fixed body 60 and the outer surface of the cylindrical side wall 53, the cylindrical shape of the fixed body 60 is a pair of first locking pieces 61 that prevent movement into the cylindrical side wall 53; The fixing body 60 is moved out of the cylindrical side wall 53 by coming into contact with the inner surface of the cylindrical side wall 53. It consists of a pair of second locking pieces 62 that prevent movement, and the entire fixture B is made of a spring material. The pair of first locking pieces 61 are integrally formed by bending.

In this state, the pair of second locking pieces 62 When the clamping force is released, the entire fixture B is almost retracted into the cylindrical side wall 53. is held elastically. After that, insert the lighting fixture body A into the embedding hole H of the fixed wall W and fix it again. Fix by operating the pair of second locking pieces 62 of tool B in a direction toward each other against the elastic force. The maximum outer width of the main body 60 is made smaller than the width of the slit 54, and this state is maintained. Now, move the fixed body 60 until the second locking piece 62 comes into contact with the inner surface of the cylindrical side wall 53. Push the fixing tool B to the outside of the cylindrical side wall 53 and prevent it from coming out of the slit 54. and move it to the fixed position. In this state, the clamping force of the pair of second locking pieces 62 is released. Then, the fixture B is held in a state in which it largely protrudes outward from the cylindrical side wall 53.

[Problem that the idea aims to solve]

In this case, the fixture B can be assembled to the lighting fixture body A in advance. However, the fixture B is attached to the cylindrical side wall 53 of the lighting fixture body A. Since it is necessary to move the slit 54 in the inner and outer directions and in the longitudinal direction of the slit 54, it is difficult to remove it. The attachment operation is still complicated, and the first locking piece is in close contact with the outer surface of the cylindrical side wall 53. Because the clearance between the outer surface of 61 and the circumferential surface of the embedding hole H is narrow, the lighting fixture itself When inserting the body A into the embedding hole H, the first locking piece 61 is pressed against the outer surface of the cylindrical side wall 53. If the first locking piece is tilted or installed a little apart, the first locking piece 61 sometimes got caught on the periphery of the hole. This invention was made in view of the above-mentioned circumstances, and its purpose is to With the fixture pre-assembled to the main body, it can be easily inserted into the mounting hole of the fixed wall. Moreover, the fixing operation required after insertion can be easily performed. The point is to make sure that
