Abstract
Official abstract text for this publication.
A sensor configured to detect displacement of a rotation angle of a shaft due to a rotation or a turn of the shaft, the sensor includes: a bearing rotatably supporting the shaft; and a housing including a bearing hole to which the bearing is fixed. The shaft and an inner circumferential surface of the bearing are fixed to each other by an adhesive agent, and an outer circumferential surface of the bearing and an inner circumferential surface of the bearing hole of the housing are fixed to each other by an adhesive agent.
First claim
Opening claim text (preview).
1 . A sensor configured to detect displacement of a rotation angle of a shaft due to a rotation or a turn of the shaft, the sensor comprising: a bearing configured to rotatably support the shaft; and a housing including a bearing hole to which the bearing is fixed, wherein the shaft and an inner circumferential surface of the bearing are fixed to each other by an adhesive agent, and an outer circumferential surface of the bearing and an inner circumferential surface of the bearing hole of the housing are fixed to each other by an adhesive agent. 2 . The sensor according to claim 1 , wherein a groove is formed on an outer circumferential surface of the shaft to which the inner circumferential surface of the bearing adheres. 3 . The sensor according to claim 1 , wherein a groove is formed on the inner circumferential surface of the bearing hole. 4 . The sensor according to claim 3 , wherein the groove formed on the inner circumferential surface of the bearing hole is located in the innermost portion in a direction in which the bearing is inserted in the bearing hole. 5 . The sensor according to claim 1 , further comprising: a generator configured to generate a predetermined detection target; a detector configured to detect the detection target generated by the generator; a substrate provided with the generator and the detector; and a member configured to affect the detection target by being rotated or turned in a detection region between the generator and the detector, wherein the housing contains the substrate and the member, one end side of the shaft extends in the housing, and the member is provided on the one end side. 6 . The sensor according to claim 5 , wherein the substrate is configured such that a first portion provided with the generator and a second portion provided with the detector are integrated with each other.
