  As described above, the buffer member 40 is fixed to the rotating lamp main body 11 by the fixing means 25, and is fixed to the attachment target member 50 by the fixing means 26. In other words, the rotating lamp main body 11 is not directly fixed to the attachment target member 50 but is fixed to the attachment target member 50 via the buffer member 40.

  Here, when the buffer member 40 is fixed, the direction in which the fixing means 26 applies to the buffer member 40 and the direction in which the fixing means 25 applies stress are opposite to each other. On the other hand, since the fixing means 25 is disposed on both sides of the fixing means 26, the buffer member 40, the body 13 and the attachment target member 50 are in good contact.

  And the fixing means 25 and the fixing means 26 are arrange | positioned so that the buffer member 40 may be inserted | pinched. That is, a part of the buffer member 40 is sandwiched between the bolt 31 and the mounting screw 32, and the body 13 side of the buffer member 40 is sandwiched between the mounting screw 32 and the bolt 31.

  In the present embodiment, the buffer member 40 is disposed on the bottom surface of the body 13, but the present invention is not limited to this. That is, the buffer member 40 may be disposed between the surface of the rotating lamp main body 11 and the surface of the attachment target member 50. In the present embodiment, screws and bolts are used as the fixing means 25 and 26 of the buffer member 40, but are not limited thereto. That is, any means that can fix the rotating lamp main body 11 via the buffer member 40 may be used.

  FIG. 2 is a bottom view of the rotating lamp 100.

  As shown in FIG. 2, an opening 46 c that penetrates in the thickness direction and an overhang 46 b that is annularly arranged around the opening 46 c are formed at the center of the buffer member 40. .

  A wiring connected to the power LED 1 shown in FIG. 1 is passed through the opening 46c. In FIG. 2, the overhanging portion 46 b is formed so as to bulge from the bottom surface 46 a of the buffer member 40, and the overhanging portion 46 b is disposed on both sides of the through hole 42 and the through hole 42. A concave portion 41 is formed. Thus, since the part into which the bolt 31 and the attachment screw 32 are inserted is formed thick, even if the vibration from the attachment target member 50 shown in FIG. The transmitted vibration is hardly transmitted to the rotating lamp main body 11 and the mounting screw 32 shown in FIG. And in FIG. 2, the upper end surface of the overhang | projection part 46b comprises a part of mounting surface 40b.

  Further, the overhanging portion 46b is annularly arranged at three positions around the opening 46c, and the attachment means 30 is annularly arranged. As described above, since a plurality of attachment means 30 are arranged, in FIG. 1, adhesion between the buffer member 40, the body 13, and the attachment target member 50 is ensured. In the present embodiment, the attachment means 30 is annularly arranged at three locations, but may be formed at one location or a plurality of locations. In the present embodiment, the rotating lamp mounting means 60 is disposed on the bottom surface side of the body 13, but is not limited thereto. For example, it may be the side surface of the body 13 or may be disposed on the glove 12 side.

  A method for attaching the rotating lamp 100 configured as described above will be described. FIG. 3 is a perspective view from the lower surface side showing a first step for mounting the rotating lamp main body 11 to the attachment target member 50. As shown in FIG. 3, in order to fix the rotating lamp main body 11, first, bolts 31 are arranged on the bottom surface side of the body 13. And the buffer member 40 is arrange | positioned at the lower end part side of this volt | bolt 31. FIG. Then, the stopper 38 is inserted into the recess 41 formed in the buffer member 40, and the mounting screw 32 inserted into the flat washer 37 is inserted into the recess 41.

  FIG. 4 is a perspective view from the upper surface side showing a first step of fixing the rotating lamp main body 11 to the attachment target member 50. As shown in FIG. 4, the recess 51 a formed in the buffer member 40 has a hexagonal cross section so as to follow the shape of the bulging portion 31 a of the bolt 31. A stopper 36 is inserted into the shaft portion 31 b of the bolt 31.

  FIG. 5 is a perspective view from the lower surface side showing a second step of fixing the rotating lamp main body 11 to the attachment target member 50. As shown in FIG. 5, the bolt 31 is inserted into the through hole 42, and the lower end portion of the shaft portion 31 b protrudes from the lower surface side of the buffer member 40. Further, the mounting screw 32 is fixed to the body 13, and the bulging portion 32 b of the mounting screw 32 presses and fixes the buffer member 40 to the body 13.

  Here, in FIG. 1, the bulging portion 32 b of the mounting screw 32 presses the buffer member 40 via the flat washer 37. For this reason, the stress applied to the buffer member 40 from the bulging portion 32 b is evenly distributed from the bottom surface of the flat washer 37. As described above, since the stress from the mounting screw 32 is suppressed, the buffer member 40 is suppressed from being excessively compressed. For this reason, even when the buffer member 40 is attached to the bottom surface of the body 13 by the mounting screw 32, the buffer function of the buffer member 40 is ensured. Since a stopper 38 for supporting the bulging portion 32b is disposed in the through hole 44 in which the mounting screw 32 is inserted, the distance between the bulging portion 32b and the bottom surface of the body 13 is determined by this stopper 38. It is prescribed by. For this reason, the upper limit of the pressing force which the bulging part 32b applies to the buffer member 40 is prescribed | regulated. For this reason, it is suppressed that the buffer member 40 is compressed too much by the attachment screw 32 and the contraction function of the buffer member 40 is inhibited.

  Then, as shown in FIG. 1, the shaft portion 31 b of the bolt 31 is inserted into the through hole 50 a formed in the attachment target member 50. Then, the nut 33 is fixed to the shaft portion 31b on the surface side of the surface of the attachment target member 50 facing the surface on which the buffer member 40 is disposed. When the nut 33 is fixed to the shaft portion 31 b in this way, the bulging portion 31 a of the bolt 31 presses the buffer member 40 toward the attachment target member 50, and the buffer member 40 is fixed to the attachment target member 50.

  Here, since the stopper 36 that supports the bulging portion 31a is inserted into the through hole 42 into which the bolt 31 is inserted, the distance at which the bulging portion 31a and the surface of the attachment target member 50 are closest to each other. And the upper limit of the pressing force that the bulging portion 31a applies to the buffer member 40 is defined. When the upper limit of the pressing force applied to the buffer member 40 by the bulging portion 31a is defined in this way, the buffer member 40 is suppressed from being excessively compressed by the bulging portion 31a, and the contraction function of the buffer member 40 is ensured. Has been.

  As described above, the mounting means 30 fixes the buffer member 40 to the rotating lamp body 11 and the fixing means 26 fixes the buffer member 40 to the mounting target member 50, so that the rotating lamp body 11 is interposed via the buffer member 40. It is fixed to the attachment target member 50.

  Further, since the buffer member 40 is fixed to the rotating lamp main body 11 or the mounting target member 50 by a plurality of mounting means 30, it is difficult for displacement such as rotation to occur, and the mounting target member 50 and the rotating lamp main body 11 are satisfactorily formed. It is fixed between. Even when vibration is generated in the attachment target member 50, the buffer member 40 absorbs the vibration, and the vibration is suppressed from being transmitted to the rotating lamp body 11. For example, when vibration occurs in a direction in which the rotating lamp main body 11 and the mounting target member 50 are brought close to or away from each other, the buffer member 40 is attached to the mounting target from the rotating lamp main body 11 by the fixing means 25 and the fixing means 26. It is pulled or compressed in the direction towards the member 50. For this reason, since the vibration generated in the attachment target member 50 is consumed by the deformation energy of the buffer member 40, the vibration generated in the attachment target member 50 is suppressed from being transmitted to the rotating lamp body 11.

  A part of the buffer member 40 is sandwiched between the fixing means 26 and the fixing means 25. For this reason, when vibration is generated in the attachment target member 50 in the direction along the surface of the attachment target member 50, the buffer member 40 positioned between the fixing means 25 and the fixing means 26 is fixed to the fixing means 25 and the fixing means 26. To expand, contract, compress, twist, or bend. As described above, when the buffer member 40 positioned between the fixing unit 25 and the fixing unit 26 is expanded or contracted or compressed, vibration energy from the attachment target member 50 is consumed by internal friction of the buffer member 40. . For this reason, it is difficult for vibration energy from the attachment target member 50 to be transmitted to the fixing means 25, and transmission of vibration to the rotating lamp body 11 is suppressed.

  In the rotating lamp mounting means 60 and the rotating lamp 100 configured as described above, even if vibration occurs in the attachment target member 50 to which the rotating lamp main body 11 is attached, the vibration is transmitted to the rotating lamp main body 11. Can be suppressed. As described above, since it is difficult for vibration to be transmitted to the rotating lamp main body 11, it is possible to extend the life of members such as the power LED 1 arranged in the rotating lamp main body 11.

  Although the embodiments of the present invention have been described as above, the embodiments disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
