And are formed via the communication portion 33. The insertion hole portion 31 is
It is circular and has a hole diameter that allows the washer 22 and the nut 23 to be inserted in the axial direction. The locking hole portion 32 has a long hole shape and is formed to have a hole width that is slightly larger than the diameter of the suspension bolt 21 that does not allow the washer 22 and the nut 23 to be axially inserted.
The communication portion 33 is formed to have the same width as the locking hole portion 32.

The bushing 41 is integrally formed of rubber or resin having elasticity, and has a substantially C-shaped fixing portion 42 fixed to the edge portion of the insertion hole portion 31 by a fixing means such as an adhesive. The fixed portion 42 is provided with a pair of locking portions 43 whose ends project into the communication portion 33 from both sides, and the communication portion 33.
There is formed a pair of positioning portions 44 which are fitted to the edge portions on both sides of and are fixed by fixing means such as adhesion.

The pair of locking portions 43 are formed in a shape along the arc of the fixed portion 42, and therefore, the tip ends thereof slightly project toward the locking hole portion 32, and the elastic deformation in the direction of the locking hole portion 32 is relatively large. The shape is made to be easy, and elastic deformation in the direction of the insertion hole portion 31 is relatively difficult. Positioning part 44
A fitting groove 47 that fits into the edge of the communication portion 33 is formed.

を通じて器具本体１の下側に挿通させる。When mounting the instrument main body 1 on the ceiling, first, the instrument main body 1 is lifted, and the washers 22 and the nuts 23 attached to the respective hanging bolts 21 hanging from the ceiling are inserted through the through holes 31 of the respective mounting holes 7. That is, the fixed portion 42 of the bushing 41
Through the lower side of the device body 1.

の状態に弾性復帰する。Subsequently, the instrument body 1 is laterally moved, and the suspension bolt 21 is fitted into the locking hole portion 32. At this time, the pair of locking portions 43 of the bushing 41 come into contact with the suspension bolt 21, but since the locking portions 43 are relatively easily elastically deformed in the direction of the locking hole portion 32, the pair of engaging portions are engaged. The suspension bolt 21 is fitted into the locking hole portion 32 while the stopper portion 43 is elastically deformed. When the suspension bolt 21 is fitted into the locking hole portion 32 and the contact between the pair of locking portions 43 and the suspension bolt 21 is released, the pair of locking portions 43 project into the communicating portion 33 in the original state. Elastic return to.

外れるのを防止できる。After the suspension bolt 21 is fitted into the locking hole portion 32, the tool body 1 is displaced when the nut 23 is tightened, and the insertion hole portion 31 is inserted into the suspension bolt 21. When the pair of locking portions 43 come into contact with the hanging bolts 21 even when the locking portion 43 moves in the direction of fitting into the insertion hole portion 31,
Since it is relatively difficult to elastically deform in the direction of, the movement of the instrument body 1 is restricted, the fitting state between the locking hole portion 32 and the suspension bolt 21 is maintained, and the instrument body 1 is suspended from the suspension bolt 21. Can be prevented from coming off.

置させることができる。Further, since the bushing 41 has the positioning portion 44 formed on the fixing portion 42, the positioning portion 44 is fitted to the edge portion of the communicating portion 33 when the fixing portion 42 is mounted in the insertion hole portion 31. As a result, the position of the fixed portion 42 inside the insertion hole portion 31 is determined, and therefore, the locking portion 43 can be positioned at the predetermined position of the communication portion 33.
