PURPOSE:To obtain an optical reflector which is constituted of the small number of components and whose reflecting mirror is not vibrated with respect to a housing even when vibration is added by adjusting the direction of the reflecting mirror by adjusting pressing force by a pair of adjustment screws toward a side surface faced to an inclined body. CONSTITUTION:The housing 10 is cylindrically formed like a glass and the position near the opened end faced to an interface is provided with a pair of screw holes 15. Besides, it is provided with an aperture 14 at the flat part. The inclined body 16 is provided with a front end part 18 where the reflecting mirror 24 is fitted, a cylindrical center part 20 obtained by fitting two rubber rings mutually separated in parallel on the circumferential surface and a back end part 22. Besides, it is integrated in the aperture housing of the housing 10 so that the reflecting mirror 24 is exposed to the opened end side. Then, the direction of the reflecting mirror 24 is adjusted by respectively screwing a pair of adjustment screws 34 in a pair of screw holes 15 of the housing 10 and pressing the front end part 18. Besides, the housing 10 and the inclined body 16 are made to adhere by injecting adhesive agent in the aperture 14 of the housing 10. |
