Abstract

Provided is an intermediate member which is arranged between a motor housing (4) and a transmission case (2) and which has multiple motor housing supporting point positions (A) and transmission case supporting point positions (B). The intermediate member is coupled to the motor housing (4) at the motor housing supporting point positions (A). The transmission case supporting point positions (B) are each arranged in an angular region formed between a motor housing supporting line (C) and a motor housing supporting center line (D) which is the center between the motor housing supporting line (C) and another motor housing supporting line (C) adjacent thereto.

Claims

1. A motor including a stator-side member and a rotor-side member, comprising:

an intermediate member arranged between a motor attachment member which supports the motor, and the stator-side member;

a plurality of stator-side support members for coupling the stator-side member and the intermediate member; and

a plurality of motor-attachment-member-side support members for coupling the intermediate member and the motor attachment member,

wherein, when a stator-side supporting line is defined as a line connecting a center of one of the plurality of stator-side support members with a rotation center of the rotor-side member, and when a center line is defined as a line evenly dividing an included angle made by the stator-side supporting line and another stator-side supporting line adjacent to the stator-side supporting line, each of the motor-attachment-member-side support members is arranged in the intermediate member within an angular region formed between the center line and the stator-side supporting line.

2. The motor according to claim 1, wherein each of the motor-attachment-member-side support members is arranged in a central portion of the angular region.

3. The motor according to claim 1, wherein the motor-attachment-member-side support members are rotatably attached to the intermediate member.

4. The motor according to claim 1, wherein the intermediate member is inserted between the stator-side member and the rotor-side member.

5. An intermediate member provided between a motor and a motor attachment member to which the motor is attached, the motor including a stator-side member and a rotor-side member, the intermediate member comprising:

a plurality of stator-side support members to be coupled to the stator-side member; and

a plurality of motor-attachment-member-side support members to be coupled to the motor attachment member,

wherein, when a stator-side supporting line is defined as a line connecting a center of one stator-side support member among the plurality of stator-side support members with a rotation center of the rotor-side member, and when a center line is defined as a line evenly dividing an included angle made by the stator-side supporting line and another stator-side supporting line adjacent to the stator-side supporting line, each of the motor-attachment-member-side support members is arranged within an angular region formed between the center line and the stator-side supporting line.

6. An intermediate member provided between a motor which includes a stator-side member, and a motor attachment member to which the motor is attached, the intermediate member comprising:

a plurality of stator-side support members to be coupled to the stator-side member; and

a plurality of motor-attachment-member-side support members to be coupled to the motor attachment member,

wherein vibration of the stator-side member vibrating in ring zeroth-mode is transmitted to the intermediate member through the stator-side support members,

a plurality of portions having a large amplitude and a plurality of portions having a small amplitude are formed in the intermediate member due to the transmission, and

the motor-attachment-member-side support members are arranged in the portions having the small amplitude.
