A recessed portion is formed in an inner wall surface of a lower portion of a reduction gear housing (a lower wall in FIG. 2) in the direction of gravity and between a bearing 44 and an outer wall of the reduction gear housing (a right side wall in FIG. 2). The recessed portion is formed to have such a depth that the recessed portion does not penetrate the reduction gear housing. The recessed portion is formed in the reduction gear housing within a given range in a circumferential direction with respect to the axis of a rack shaft serving as the center. A moisture sensor is mounted in the recessed portion to detect water infiltrating into a housing. The moisture sensor has a transmission circuit that operates using a water battery as a power supply source. The water battery generates power when water flows into the water battery.
