Motor apparatus having improved connector unit

A motor apparatus provided with a connector unit to which an external connector for supplying driving current to a motor section is connected, wherein

• the motor section comprising a motor case and four magnets each formed into an approximately arc shape in cross section, wherein the motor case has an approximately oval-shaped cross section which has a pair of arc-shaped portions and a pair of straight portions, the four magnets are housed in the motor case, and fixed along a circumferential direction of the motor case at intervals of 90 degrees,
• the connector unit comprises:
• a base portion provided with an opening portion in which an armature shaft extending from the motor section is inserted;
• a connector connecting portion provided with a plug-in hole in which the external connector is plugged;
• and
• a plurality of conductive members arranged over the base portion and the connector connecting portion,
• wherein the conductive members respectively include connector-side connecting portions connected to the external connector so as to face the connector connecting portion from a first direction reversed to a plug-in direction of the external connector to the plug-in hole, base-side connecting portions connected to terminals or wirings provided in the base portion, and intermediate portions through which the connector-side connecting portions and the base-side connecting portions are electrically connected to each other,
• wherein the connector-side connecting portions of the respective conductive members are respectively inserted into a plurality of insertion holes provided at positions different from each other in a second direction intersecting the first direction,
• wherein the base-side connecting portions of the conductive members are respectively arranged at the same position in the second direction,
• the intermediate portions of the conductive members are respectively disposed at positions different from each other in the second direction, and
• the connector unit has supporting faces which are different in position from each other in the second direction, and which support the respective intermediate portions of the conductive members,
• wherein the four magnets are respectively arranged in the vicinity of four corners between the arc-shaped portions and the straight portions so that an inner face of one of the straight portions is partially overlapped with parts of two magnets, and an inner face of the other of the straight portions is partially overlapped with parts of the remaining magnets,
• each of the four magnets has a thick portion and two thin portions smaller than in thickness than the thick portion, the thin portions being integrally formed on both sides of the thick portion in the circumferential direction of the motor case,
• gaps are respectively formed between the thin portions of the four magnets and the arc-shaped portions of the motor case, and
• gaps are respectively formed between the thin portions of the four magnets and the straight portions of the motor case.
