摘要： A housing and a rotary shaft of a motor are formed of non-magnetic material. A soft magnetic member is provided between a first axial end surface of a fixed core and a bearing. The soft magnetic member is provided on the fixed core side relative to the first bearing thereby to suppress magnetic flux leaking to a vicinity of one end part of the rotary shaft by leading the magnetic flux, which is generated from a rotor, to the rotor core through the fixed core and a casing. A magnetic angular position sensor fixed to one end part of the rotary shaft can detect a magnetic angular position of the rotor accurately without being affected by external magnetic field. As a result, noise generated by vibration of the motor can be suppressed.

摘要： A rotor has a projection part projected from an inner wall of a central hole part toward a central axis and a rib part defined between opening parts adjacent with each other in a circumferential direction. A first imaginary straight line is defined to extend from the central axis outward in a radial direction through a center of the projection part. The projection part is formed so that the first imaginary straight line passes the opening part. A second imaginary straight line is defined to extend from the central axis outward in the radial direction through a center of the rib part. The rib part is formed so that the second imaginary straight line passes a center of a pole part or an intermediate position between pole parts adjacent with each other in the circumferential direction.

摘要： A conductive pattern, as an antenna, includes: a radiating element formed in an inverted F shape; and a feeding element for indirectly feeding power to the radiating element. The radiating element includes a main body, a short circuit part, and a powered part. The main body is a member longer than the short circuit part and the powered part. The short circuit part is connected to the main body at right angle at one end of the main body. The powered part extends from a middle of the main body in a direction perpendicular to the main body so as to have a predetermined distance from, for example, the short circuit part. The feeding element is formed to face the powered part below the powered part.
