PROBLEM TO BE SOLVED: To improve maintainability while reducing the number of components.SOLUTION: A motor device includes: a first radial-direction positioning surface 45b which is provided further outside in the radial direction than a support pin 70 of a pin fixing part 42 and faces an output member 50; a second radial-direction positioning surface 53b which is provided further outside in the radial direction than the support pin 70 of the output member 50 and faces the pin fixing part 42; and an O-ring 60 for sealing the inside and the outside of a housing provided between the first radial-direction positioning surface 45b and the second radial-direction positioning surface 53b. Thereby, one O-ring 60 can prevent an entering object W from entering the housing from both end sides of the support pin 70. The O-ring 60 is separated from the support pin 70, and accordingly, a high temperature of the support pin 70 can be suppressed from being transmitted to the O-ring 60, even if the support pin 70 is made from a metal. |
