Abstract
A sensor and an electronic device are provided. The sensor includes a setting part and a seal ring in an annular shape. The setting part changes a setting of a sensor main body. The seal ring is provided to surround a shaft of the setting part and seals a gap between the shaft and a housing. The seal ring has a curved surface part and a pair of end parts. The curved surface part is curved convexly in a cross-sectional view. The pair of end parts have a shape different from the curved surface part and extend in an axial direction of the seal ring, on two sides of the curved surface part in the axial direction of the seal ring.
Claims12
A sensor, which is a sensor housing in a housing at least one of a light projecting part that emits light and a light receiving part that receives light, the sensor comprising:
- a setting part changing a setting of a sensor main body in response to an input operation from outside and having a shaft inserted into the housing;
- and
- a seal ring in an annular shape, provided to surround the shaft and sealing a gap between the shaft and the housing,
- wherein the seal ring has
- a curved surface part that is curved convexly in a cross-sectional view, and
- a pair of end parts that have a shape different from the curved surface part and extend along an axial direction of the seal ring, on two sides of the curved surface part in the axial direction of the seal ring.
An electronic device, which is an electronic device comprising a housing and a substrate housed in the housing and mounted with a control circuit, the electronic device comprising:
- a setting part changing a setting of an electronic device main body in response to an input operation from outside and having a shaft inserted into the housing;
- and
- a seal ring in an annular shape, provided to surround the shaft and sealing a gap between the shaft and the housing,
- wherein the seal ring has
- a curved surface part that is curved convexly in a cross-sectional view, and
- a pair of end parts that have a shape different from the curved surface part and extend along an axial direction of the seal ring, on two sides of the curved surface part in the axial direction of the seal ring.
