Since the mounting base fixed to the mounting target is separate from the mounting base, the arm may be connected to the mounting base after fixing the mounting base to the mounting target. It will be easier. Moreover, the receiving cylinder portion of the mounting base is formed in a shape in which a large mouth portion and a small mouth portion having different opening areas are arranged vertically along the center line direction, and the outer peripheral shape of the insertion portion of the arm is larger than that of the large mouth portion of the receiving cylinder portion. By being formed in a shape having a large diameter portion that is also a small size and a larger size than the small mouth portion and a small diameter portion that is a smaller size than the small mouth portion,
When the insertion part of the arm is inserted into the receiving cylinder part provided on the mounting base from above, the large diameter part of the insertion part of the arm is locked between the large mouth part and the small mouth part of the receiving cylinder part, and the lamp and the arm The arm and the lamp can be temporarily attached to the mounting table by a simple operation of inserting the insertion portion into the receiving cylinder portion. Also, the mounting screw screwed to the large diameter portion of the insertion portion is engaged with the notch groove formed facing the opening edge of the large mouth portion of the receiving cylinder portion, and the outer peripheral surface of the large diameter portion and the head of the mounting screw are engaged. The arm can be fixed so that the arm does not come off from the mounting base by sandwiching the peripheral portion of the notch groove between the arm.

The diameter portion 31b (corresponding to the lower end of the insertion portion 21 in the embodiment) is formed integrally. Between the large-diameter portion 21a and the small-diameter portion 21b, the large-diameter portion 21a is moved to the small-diameter portion 2 so as to correspond to the tapered cylinder 31c formed in the receiving cylinder portion 31.
Tapered portion 21 that gradually reduces the outer diameter toward 1b
c is formed. Here, the diameter of the large mouth 31a is D

Therefore, when the insertion portion 21 is inserted into the receiving tube portion 31, the lower end of the large diameter portion 21a is locked by the inner peripheral surface of the tapered tube 31c, and the arm 2 does not fall down. Here, if the angle of inclination of the inner peripheral surface of the tapered cylinder 31c with respect to the center line and the angle of inclination of the tapered portion 21c with respect to the center line of the outer peripheral surface are substantially matched, the contact area between the tapered cylinder 31c and the tapered portion 21c can be reduced. The strength of fixing the insertion portion 21 to the receiving tube portion 31 can be increased.

By the engagement of the notch 2 with the notch groove 38, the rotation of the insertion portion 21 with respect to the receiving cylinder portion 31 is stopped. Moreover,
When the mounting screw 22 is tightened, the peripheral portion of the notch groove 38 is sandwiched between the outer surface of the insertion portion 21 and the head of the mounting screw 22, and the arm 2 is prevented from falling out of the receiving tube portion 31. Will be done. In this manner, the arm 3 can be firmly fixed to the mounting base 3 only by using the mounting screw 22 and the notch groove 38.

The arm 1 can be fixed to the object to be mounted separately from the arm 2, and it is not necessary to support the relatively heavy lamp 1 or the arm 2 in the mounting operation, and the mounting operation is facilitated. In particular, when working at a high place such as when the lamp 1 is a security light, remove the heavy objects of the lamp 1 and the arm 2 when mounting the mounting base 3 to the mounting object,
Since the arm 2 can be temporarily held by simply inserting the arm 2 into the mounting base 3 after fixing the mounting base 3, the operation can be performed safely.

Is different from the first embodiment. That is, the stop projection 39 is formed so as to prevent the head of the mounting screw 22 from moving upward, and prevents the arm 2 from moving upward with respect to the mounting base 3 even if the mounting screw 22 is slightly loosened. It is banned. By providing such a stop projection 39, the arm 2 with respect to the mounting base 3 is provided.
The reliability of the connection can be improved. The other configuration is the same as that of the first embodiment, and the description is omitted.

利点がある。As described above, according to the present invention, since the arm connected to the lamp and the mounting base fixed to the mounting object are provided separately, the arm is fixed after the mounting base is fixed to the mounting object. May be connected to the mounting table, and there is an advantage that the work of fixing the mounting table to the mounting target is facilitated. Also,
The receiving cylinder portion of the mounting base is formed in a shape in which a large mouth portion and a small mouth portion having different opening areas are arranged vertically along the center line direction, and the outer peripheral shape of the insertion portion of the arm is smaller than the large mouth portion of the receiving cylinder portion. Since it is formed in a shape that has a large diameter portion that is larger in size than the small mouth portion and a small diameter portion that is smaller than the small mouth portion, the arm is inserted into the receiving cylinder portion provided on the mounting base. If the part is inserted from above, the large diameter part of the insertion part of the arm is locked between the large mouth part and the small mouth part of the receiving cylinder part, and the weight of the lamp and the arm is received by the receiving cylinder part of the mounting base. Therefore, there is an advantage that the arm and the lamp can be temporarily attached to the mounting table by a simple operation of inserting the insertion portion into the receiving tube portion. Further, a mounting screw screwed to the large diameter portion of the insertion portion is engaged with a notch groove formed facing the opening edge of the large mouth portion of the receiving cylinder portion, and the outer peripheral surface of the large diameter portion and the head of the mounting screw are engaged. Since the peripheral portion of the cutout groove is sandwiched between the mounting base and the mounting base, the arm can be fixed so as not to be detached from the mounting base. Even though the mounting base and the arm are separate bodies, both are firmly connected. There is an advantage that can be.
