A sensor apparatus has a sensor protruding portion and a sensor support which are formed integrally with each other. The sensor apparatus also includes a retainer, an inner seal, an outer seal, a fastener, and a friction reducer. The retainer is rotatable relative to the sensor protruding portion and the sensor support. The inner seal is disposed between the sensor support and the retainer. The outer seal is disposed between a wall and the retainer. The fastener includes a fitting groove formed in one of the sensor support and the retainer and a protrusion formed on the other of the sensor support and the retainer. The protrusion is engaged in the fitting groove to achieve installation of the sensor apparatus in the wall. The friction reducer works to increase an interval between the sensor support and the retainer to reduce a degree of friction produced by the inner seal when the sensor support is turned relative to the retainer to install the sensor apparatus in the wall. This permits a sensor installing operator to easily confirm completion of his or her work to install the sensor apparatus in the wall.
