<Modification example>
1. 1. Mounting portion and mounted portion In the first embodiment, the mounting portion is composed of mounting portions 345 and 346 of the lamp fixture 34 mounted on the fixture side base 33, and the mounted portion is integrated with the lamp side base 51 of the lamp fixture 5. It is composed of a back stretching portion 519 provided in.
However, when the lamp is brought closer to the mounting fixture in the mounting direction, the mounting portion and the mounted portion are elastically deformed in the direction in which at least one of the mounting portion and the mounted portion intersects the mounting direction and engages with each other. For example, when it is not characterized in that the mounting portion is integrally provided on the lamp side base, the fixture side base is an integrally molded product in which the mounting portion is integrally provided on the fixture side base portion, and the lamp side base is used. The attached portion of the attached tool provided as a separate member may be elastically deformable at the time of attachment. Further, the mounting portion and the mounted portion may be elastically deformed and engaged with each other.
Further, although the mounting portions 345 and 346 are provided on the lamp fixture mounting tool 34 which is a separate member from the fixture side base 33, they may be provided integrally with the fixture side base 33 (as an integrally molded product). Similarly, the attached portion 519 is integrally provided with the lamp side base 51, but if it is not characterized in that the attached portion is integrally provided with the lamp side base, the attached portion 519 is a different material from the lamp side base. It may be provided on the fixture.

In the first and third embodiments, the mounting directions of the mounting fixtures 3 and 3C of the lighting fixtures 5 and 5C are the front and back directions. The mounted portion is used as an engaging portion that engages with the engaging groove portion, and the lamp is rotated around the engaging portion in a state where the engaging portion of the lamp is engaged with the engaging groove portion of the mounting fixture to form the mounting fixture. The other mounting portion 346 of the mounting fixture 3 may be elastically deformed so that the mounted portion 519 of the lamp 5 can be mounted.

The mounting portions 345, 346 and the mounted portion 519 had a shape of being recessed inward in the direction orthogonal to the vertical direction (short direction), but were formed on the outer side in the orthogonal direction (short direction). It may have a protruding shape, or it may have a shape that is a combination of a recess and a protrusion. That is, the shape may be such that the mounting portion and the mounted portion can engage with each other.

2. Lamp-side base The lamp-side base may or may not have another functional portion when the light source mounting portion and the mounted portion are integrally provided. Other functional parts include a groove portion 518 for mounting the translucent cover 52, an upright portion 513 for positioning the power supply unit 55, a groove portion 515 into which a screw can be screwed, and the like.
However, when a pultruded product or the like is used as the lamp side base, it is preferable to have many functional parts from the viewpoint of reducing the assembly man-hours and the number of parts.

3. 3. Instrument-side base The instrument-side base 33A has a terminal block 35A (terminal block attachment 37A), a connector 38A, and a folded-back portion 333A, 334A for attaching a support plate 39A. The terminal block 35A (terminal block attachment 37A), connector 38A, and support plate 39A may be attached to the instrument base by another method, except for the case where it is attached to the side base. However, when one or more members are attached to the instrument side base, it is preferable to attach using the folded-back portion from the viewpoint of reducing the assembly man-hours and the number of parts.
The instrument-side base 33 has a through hole 332a as an example of a recess in which the positioning portion 374 of the terminal block attachment 37 is bent, but may have a recess, for example. Further, the instrument-side base has a pair of protrusions protruding to the front side, and the positioning portion may be bent between the protrusions. In this case, a recess is formed between the pair of protrusions.
