In this state, when the rotating frame body 23 is rotated about the rotating shaft 29 and inserted through the opening of the instrument main body IO, the guide portion 40 of the rotating guide body 32 engages with the locking protrusion 44 of the spring body 43. It serves as a guide when contacting and getting over the locking protrusion 44 of the spring body 43 without colliding with the locking protrusion 44, and furthermore, the rotation of the rotation guide body 32 allows the locking part 35 to be moved over. Even if the locking protrusion 44 of the spring body 43 falls into the locking hole 38 of the spring body 43, the locking hole 38 is guided by the guide piece 39 so that the position of the locking protrusion 44 of the spring body 43 can be adjusted with a light rotational force. It's too hot. When the rotating frame 23 is inserted into the instrument main body 10, the lateral vibration prevention protrusions 31 of the rotating frame 23 slide inside both sides of the instrument body 10, preventing lateral vibration.

3, the reflector plate 15 is projected from the opening of the instrument body 10, and the orientation of the irradiation opening 16 of the reflector plate 15 is changed to adjust the irradiation direction. At this time, the rotating frame 23
The locking portion 35 of the rotation guide body 32 is rotatably supported at 0.
The installation of the instrument main body 10 is performed using the spring body 43 provided in the tool 4 and 2.
The rotating frame 23 and the reflecting plate 15
The weight of the spring body 43 facilitates engagement and disengagement between the locking protrusion 44 of the spring body 43 and the locking hole 38, and the locking protrusion 44 of the spring body 43 engages with the locking hole 38 at the set position of the reflection plate 15. The rotating position is held, and the reflecting plate 15 is held in a predetermined irradiation direction by the rotating position with respect to the instrument body 10. When the reflector 15 is inserted into the instrument main body IO, the locking protrusion of the spring body 43 is inserted into the locking hole 38 of the locking portion 35 by rotating the rotation guide body 32 in the same manner as in the above-described assembly. Even if 44 falls, the guide piece 39
As a result, the locking hole 38 passes through the position of the locking protrusion 44 of the spring body 43 with a light rotational force.
そして、反射板１５には回動によって外力を受けること
なく、反射板１５は変形されることがない。Further, the reflection plate 15 is not subjected to any external force due to the rotation, so that the reflection plate 15 is not deformed.
さらに、反射板１５の回動、特に、反射板１５を器具本
体１０内に開口部から嵌入させるときに、反射板１０が
器具本体１０と摺擦することがない。Furthermore, when the reflector 15 rotates, particularly when the reflector 15 is inserted into the instrument body 10 through the opening, the reflector 10 does not rub against the instrument body 10.
