Motor apparatus

A motor apparatus including:

• a motor portion provided with a housing in which a rotation shaft is provided;
• a power supply member which is provided inside the housing;
• and
• a connector member which is connected to the power supply member, and supplies a drive current from an external connector to the power supply member so that the drive current rotates the rotation shaft, wherein
• the housing is provided with an assembling hole,
• the connector member is provided with an assembly main body to be inserted along a center line of the assembling hole,
• the assembling hole is symmetric with respect to a plane passing through the center line of the assembling hole,
• the assembly main body has an outer periphery which is symmetric with respect to a plane passing through an center line of the assembly main body,
• a pair of connector-side conductive members is provided to the connector member, and has a pair of connector-member-side terminals which is provided on a distal end side in an insertion direction of the assembly main body, and symmetrically disposed with respect to the plane passing through the center line of the assembly main body,
• a pair of brush-side conductive members is provided to the power supply member, and has a pair of power-supply-member-side terminals which is symmetrically disposed with respect to the plane passing through the center line of the assembling hole, and connected to the connector-member-side terminals,
• when the assembly main body is inserted in the assembling hole, the center line of the assembly main body is aligned with the center line of the assembling hole,
• the connector member is further provided with a cap portion having an outer periphery provided with:
• a pair of first engaging portions symmetrically disposed with respect to the center line of the assembly main body;
• and a pair of second engaging portions symmetrically disposed with respect to the center line of the assembly main body,
• the housing has:
• a pair of first engaged portions which is symmetrically disposed with respect to the center line of the assembling hole, and respectively engaged with the first engaging portions of the connector member when the assembly main body is inserted in the assembling hole;
• and a pair of first engaged portions which is symmetrically disposed with respect to the center line of the assembling hole, and respectively engaged with the first engaging portions of the connector member when the assembly main body is inserted in the assembling hole,
• a sensor magnet is placed on the rotation shaft,
• a rotation sensor is provided in the connector member, and
• the rotation sensor is arranged to face the sensor magnet at an outer side in a radial direction of the rotation shaft with the connector member directed in a first direction, or with the connector member directed in a second direction opposite to the first direction, and
• when the assembly main body is inserted in the assembling hole, the rotation sensor selectively takes two positions symmetrically defined with respect to the center line of the assembling hole by changing the direction of the connector member.
