Abstract

A motor includes: a lid including an opening; a bracket including a projecting part; and a terminal extending from the projecting part. A part of the bracket is covered by the lid. The projecting part projects from the opening of the lid.

First claim

The invention claimed is:

1. A connection structure of a motor and a substrate comprising:
a motor, and
a substrate, wherein the motor includes
a lid including an opening;
a bracket including a projecting part; and
a terminal extending from the projecting part, wherein
a part of the bracket is covered by the lid, and
the projecting part projects from the opening of the lid,
the substrate includes a surface opposing the lid,
the lid includes a surface opposing the substrate,
the substrate is supported by the projecting part,
the surface of the substrate is separated from the surface of the lid, and
the substrate is connected to the terminal.

2. The connection structure of a motor and a substrate according to claim 1 , wherein the motor includes
a frame; and
a rotary shaft including one end part projecting from the frame and another end part supported by the lid, wherein
the lid covers a surface of the bracket at a side of the another end part of the rotary shaft,
the terminal extends from the projecting part in a direction from the one end part of the rotary shaft toward the another end part, and
the projecting part includes a hole part and a wall part surrounding the terminal, the terminal being inserted into the hole part.

3. The connection structure of a motor and a substrate according to claim 2 , wherein
a gap is formed between the wall part and the terminal in a direction intersecting the rotary shaft, and
the gap extends in a rotary shaft direction.

4. The connection structure of a motor and a substrate according to claim 1 , wherein the motor includes
a commutator; and
a brush that comes into contact with the commutator.

5. The connection structure of a motor and a substrate according to claim 1 , wherein
the projecting part includes a hole part and a wall part surrounding the terminal, the terminal being inserted into the hole part,
the lid covers the surface of the bracket at a side of the substrate,
the terminal is inserted into the hole part in a direction from the bracket toward the substrate,
a gap is formed between the wall part and the terminal in a direction intersecting a rotary shaft, and
a member electrically connecting the substrate and the terminal is located in the gap.
