PROBLEM TO BE SOLVED: To prevent movement and rattling of a motor in a housing to securely fix the motor with a simple structure in a motor unit.SOLUTION: In a motor unit 10, a housing chamber 20 capable of housing a motor 14 is formed in a housing 12 and ribs 26 which protrude to the radial inner side and contact with an outer peripheral surface of the motor 14 are formed on an inner peripheral surface of the housing chamber 20. A protruding part 40 protruding to the radial outer side is formed in an end cap 38 attached to the other end part of the motor 14. The protruding part 40 is inserted into a recessed part 42 of the housing 12 to be engaged therewith. In the structure, the ribs 26 prevent the motor 14 from falling in the housing 12. Further, the protruding part 40 is engaged with the recessed part 42 to restrict rotational displacement of the motor 14 in the housing 12.SELECTED DRAWING: Figure 2 |
