Motor damping structure for actuator device

1. A motor damping structure for an actuator device comprising:

a motor housing including a drive motor therein; and

a casing including an upper actuator case and a lower actuator case to accommodate the motor housing therebetween, the casing including a motor support section formed integrally in at least one of the upper actuator case and the lower actuator case to support the drive motor by contacting an outside surface of the motor housing, the motor support section having an elastic contacting member protruding from the at least one of the upper actuator case and the lower actuator case to contact one of an upper slanted surface and a lower slanted surface of the motor housing,

at least one of an upper face section and a lower face section of the motor housing having a generally flat surface, and the one of the upper slanted surface and the lower slanted surface of the motor housing is a chamfered shape surface disposed adjacent to the flat surface.

2. The motor damping structure for an actuator device as recited in claim 1 , wherein

the motor support section has a reinforcing rib formed integrally on a corner section of the at least one of the upper actuator case and the lower actuator case, and the elastic contacting member is a thin plate member protruding from a slanted surface of the reinforcing rib.

3. The motor damping structure for an actuator device as recited in claim 2 , wherein

the elastic contacting member has a thickness that is smaller than the reinforcing rib.

4. The motor damping structure for an actuator device as recited in claim 2 , wherein

the reinforcing rib has a seat section including the slanted surface, with the seat section having a thickness smaller than a thickness of the reinforcing rib and larger than a thickness of the elastic contacting member.

5. The motor damping structure for an actuator device as recited in claim 2 , wherein

a surface of the reinforcing rib is substantially flush with a surface of the elastic contacting member.

6. The motor damping structure for an actuator device as recited in claim 1 , wherein

the motor support section is disposed between a top wall and a first side wall of the upper actuator case and between the top wall and a second side wall of the upper actuator case facing the first side wall, and

a distance between the first side wall and the second side wall of the upper actuator case is larger than a height of the first side wall or the second side wall.

7. A motor damping structure for an actuator device comprising:

a motor housing including a drive motor therein;

a casing including an upper actuator case and a lower actuator case to accommodate the motor housing therebetween, the casing including a motor support section formed integrally in at least one of the upper actuator case and the lower actuator case to support the drive motor by contacting an outside surface of the motor housing, the motor support section having an elastic contacting member protruding from the at least one of the upper actuator case and the lower actuator case to contact one of an upper slanted surface and a lower slanted surface of the motor housing, the motor support section further having an additional elastic contacting member protruding from the at least one of the upper actuator case and the lower actuator case, the additional elastic contacting member being disposed on an opposite side from the elastic contacting member with respect to the motor housing; and

a latching member that latches the upper actuator case and the lower actuator case together, the latching member being coupled to an exterior surface of the casing and positioned on an extension line of a straight line passing through both the elastic contacting member and the additional contacting member such that the latching mechanism elastically deforms in a direction along the extension line.
