止具5の勝手な回転を阻止する意味を持つ。DESCRIPTION OF THE PREFERRED EMBODIMENTS A description will be given with reference to FIGS. The illustrated fluorescent lamp apparatus according to the present invention is a reflector
It is a straight tube type fluorescent lamp fixture attached. The fluorescent lamp device includes a device main body 1. Reflector mounting bracket 4 to be fixed to instrument body 1
Is provided. A reflection plate 2 is provided on the lower surface side of the instrument body 1. There is provided a rotary locking tool 5 for detachably mounting the reflector 2 to the reflector mounting bracket 4. These points are the same as before. The rotary locking device 5 of the present invention includes a conductive component 54 detachably engaged with the reflector mounting bracket 4 and an insulating component 52 covering a lower portion of the conductive component 54. The insulating part 52 includes a shaft part 53 having an elliptical cross section and a knob part 51 below the shaft part 53. A pair of contact portions 55 that are integral with the conductive component 54 and are exposed around the shaft are provided on the shaft portion 53. Shaft 53 on reflector 2
Is provided with a long through hole 21 penetrating therethrough. Reference numeral 3 denotes a lamp socket, on which a straight tube-type fluorescent lamp (not shown) is detachably mounted. Shaft portion 5 to which a pair of contact portions 55 is attached
The relative shape of the through hole 53 is determined such that the pair of contact portions 55 is pressed against the edge of the through hole 21 in a normal rotation phase in which the longitudinal directions thereof are orthogonal to each other. Thus, the reflector 2 is electrically connected to the appliance main body 1 via the through hole 21, the contact portion 55, the conductive component 54, and the reflector mounting bracket 4. Supplement the explanation. The role of the insulating component 52 covering the lower part of the conductive component 54 is to prevent the reflection plate 2 from being damaged, and to soften the knob 51 to make it easy to grasp. Since the upper part of the conductive component 54 is exposed, it is electrically connected to the reflector mounting bracket 4. The reason why the through-hole 21 has a long hole shape is to allow the knob portion 51 to be freely inserted. Knob part 5 in that relation
1 must be slightly smaller than the through hole 21.
Therefore, the through hole 21 is closed as D> E, and the appearance is reduced. Of course, A> C must be satisfied. However, it is possible to set A ≒ B without A <B. Since the shaft portion 53 entering the through hole 21 is in an elliptical state with a major axis B and a minor axis C, for example, and A> C, loose insertion is possible. Then, when it is rotated by approximately 90 degrees via the knob 51, it is not possible to make A> B, so that the through hole 21 and the rotary locking tool 5 are pressed against each other at that location. In the present invention, the contact portion 55
To form The contact portion 55 is formed by exposing the portion of the conductive component 54 without being covered by the conductive component 54. Since this principle works in the contact part 55 pressure welding, it is a strong pressure welding in which an electrical connection is ensured. It also has the effect of preventing the free rotation of the rotary lock 5.

て、コストダウンに役立つ。According to the present invention, a pair of conductive contact portions which are exposed around the shaft of the rotary locking device are provided on the shaft so that electrical connection can be appropriately made to the through holes in the reflector. It is something devised. This ensures that the electrical connection between the appliance body and the rotary locking device and the reflector is made with little or no new cost and with little or no additional effort. Can be. Therefore, it is useful for cost reduction.
