る。 A rotation speed and rotation angle position detection unit (hereinafter referred to as the unit) 6, which is fixed to the engine and includes a housing 1 having an opening 2 on the side opposite to the engine, a light emitting element 3, a light receiving element 4, and a control circuit section 5, is connected to the housing. It is fixed at 1. An engine side end 8 of a shaft 7 which passes through the center of the housing 1 and the unit 6 and is rotationally driven by the engine is supported by a ball bearing 9. A rotor plate 10 having a plurality of slits on its outer periphery is held between two rotor shafts 11 and 12 fitted to the shaft 7, and is integrated with the rotor shafts 11 and 12 into the shaft 7 by bolts 13. A bearing base 15 is fixedly attached to the opening 2 of the housing 1 with screws 21, which is formed by integrally molding a bearing mounting cylindrical portion 19 and a rotating body end cover portion 20 by die casting or the like. An oil-impregnated bearing metal 14 is attached to the bearing mounting cylindrical portion 19, and the oil-impregnated bearing metal 1
An oil absorbing member 16 such as felt is attached to the engine side end of 4 with a pressing spring 17. The oil-impregnated bearing metal 14 pivotally supports the rotor shaft 12, thereby pivotally supporting the end portion 18 of the shaft 7 on the side opposite to the engine. Further, the bearing base 15 is provided with a communication hole 23 that communicates the space 22 inside the rotating body end cover 20 with the housing opening 2 side.

果がある。 In the above configuration, when the bearing base 15 is attached, the air inside the bearing metal 14 and the air in the space 22 pass through the communication hole 23 to the housing 1.
Since it escapes to the side, it has the effect of preventing air compression.
本考案によれば、塵埃の浸入が無く、かつ部品
点数を増加することなく空気圧縮を防止できると
いう効果がある。 According to the present invention, there is an effect that air compression can be prevented without infiltration of dust and without increasing the number of parts.
