<p>PROBLEM TO BE SOLVED: To obtain a motor actuator in which a pulse plate and a sliding contact are not melted due to high temperatures by preventing the lack of grease between the pulse plate and the sliding contact. SOLUTION: The first electrically conductive part 194A provided for the pulse plate 192 of a motor actuator comes into contact with an input contact 196A, the second electrically conductive part 194B comes into contact with an output contact 196B, and it is possible to obtain pulse signals by the rotation of the pulse plate 192. A slit part 80 is provided for the first electrically conductive part 194A by exposing a resin material, and the input contact 196A comes into contact with the slit part 80 as well. Grease is easily accumulated in the boundary part of the slit part 80, and the slit part 80 has the function of accumulating grease. Therefore, even if the pulse plate 192 is continuously rotated, and the first electrically conductive part 194A and the input contact 196A are continuously slid, as grease does not run out between both of them, and they are not melted due to high temperatures, it is possible to maintain the original performance of position detection.</p> |
