Abstract

The purpose of the invention is to provide a motor in which it is possible to efficiently construct a structure wherein a terminal part of a motor body is covered by a terminal cover. This terminal cover (7) is a resin molded article integrally including a first member (8) fixed to a motor body (40), a second member (9) that covers the first member (8), and a hinge part (70). Thus, the first member (8) and the second member (9) can be engaged with one another by first fixing the first member (8) to the motor body (40), and then rotating the second member (9) at the hinge part (70) and covering the first member (8) with the second member (9). Thus, the number of components can be reduced compared to cases where the first member (8) and the second member (9) are constructed as separate members, and the task of attaching the second member (9) to the first member (8) can be performed efficiently.

First claim

The invention claimed is:

1. A motor comprising:
a motor main body in which a rotation shaft is protruded toward an output side; and
a terminal cover which covers a terminal part provided on one side in a first direction of the motor main body from the one side in the first direction;
wherein the terminal cover is a resin molded product integrally comprising:
a first member which is fixed to the motor main body on the one side in the first direction;
a second member which covers the first member from the one side in the first direction; and
a hinge part which turnably connects the second member with the first member around an axial line extended in a second direction intersecting the first direction; and
wherein the second member comprises an engaging part structured to fix the second member to the first member, and
the engaging part comprises at each of end parts on both sides in the second direction of the second member:
a first engaging part which is provided at a position separated from the hinge part on one side in a third direction intersecting the first direction and the second direction so as to be abutted with a first engaging protruded part of the first member from another side in the first direction and from one side in the third direction; and
a second engaging part which is provided at a position separated from the first engaging part on the one side in the third direction so as to be abutted with a second engaging protruded part of the first member from the another side in the first direction and from another side in the third direction.

2. The motor according to claim 1 , wherein
the first member holds a wiring board which is electrically connected with terminals of the terminal part, and
the second member covers the wiring board from the one side in the first direction.

3. The motor according to claim 2 , wherein the first member comprises:
a circuit board support face which supports the wiring board from the other side in the first direction; and
a circuit board holding pawl which is protruded from the circuit board support face to the one side in the first direction to be abutted with a face on the one side in the first direction of the wiring board.

4. The motor according to claim 3 , wherein an end part of the wiring board is formed with a recessed part to which the circuit board holding pawl is fitted at an overlapped position with the circuit board holding pawl.

5. The motor according to claim 4 , wherein the first member comprises a positioning protruded part which is protruded from the circuit board support face to the one side in the first direction to be abutted with an end part of the wiring board.

6. The motor according to claim 5 , wherein the second member comprises a circuit board holding part which is protruded to the other side in the first direction to be abutted with the wiring board from the one side in the first direction.

7. The motor according to claim 5 , wherein the wiring board holds a connector.

8. The motor according to claim 4 , wherein the second member comprises a circuit board holding part which is protruded to the other side in the first direction to be abutted with the wiring board from the one side in the first direction.

9. The motor according to claim 4 , wherein the wiring board holds a connector.

10. The motor according to claim 3 , wherein the second member comprises a circuit board holding part which is protruded to the other side in the first direction to be abutted with the wiring board from the one side in the first direction.

11. The motor according to claim 3 , wherein the wiring board holds a connector.

12. The motor according to claim 2 , wherein the second member comprises a circuit board holding part which is protruded to the other side in the first direction to be abutted with the wiring board from the one side in the first direction.

13. The motor according to claim 2 , wherein the wiring board holds a connector.
