摘要： A rotor includes first and second rotor cores, a field magnet, interpole magnets and holding members. The first and second rotor cores each have claw-like magnetic poles arranged in the circumferential direction in an outer periphery of a core base at even intervals and formed to protrude radially outward. The field magnet is placed between the core bases in the axial direction of the rotor and magnetized in the axial direction to cause the magnetic poles of the first and second rotor cores to function as first and second magnetic poles, respectively. The interpole magnets are each arranged between a circumferentially adjacent pair of the magnetic poles and magnetized in the circumferential direction so as to have the same polarity as the magnetic poles, which are opposed thereto in the circumferential direction. The holding members hold the interpole magnets to restrict radially outward movement of the interpole magnets.

摘要： A brushless motor including a stator having teeth and a rotor having magnetic pole portions is disclosed. The magnetic pole portions are arranged to have the same polarities as each other. The rotor includes gaps that function as magnetic resistance at circumferential ends of each of the magnetic pole portions so that an iron core portion is formed between the circumferentially adjacent magnetic pole portions. Magnetic flux of the magnetic pole portions passes through the iron core portion along the radial direction. The gaps include a first gap located on the leading end of the magnetic pole portion in the rotation direction of the rotor and a second gap located on the trailing end of the magnetic pole portion in the rotation direction of the rotor. The circumferential width of the first gap is set to be greater than the circumferential width of the second gap.

摘要： A centrifugal braking apparatus for a baitcasting reel comprises a spool, pivot shafts, brake levers, and a ring-shaped braking member. The spool is rotatably supported between both side plates of a reel main body. Each of the pivot shafts is disposed on the spool so as to be arranged apart from a rotation axis of the spool in a radius direction thereof and extended at right angles to a straight line parallel with the rotation axis of the spool. Each of the brake levers has a tip end portion and a root end portion that is pivotably supported by the pivot shaft so that the tip end portion of the brake lever is movable toward a standard plane, which includes a central axis of the pivot shaft and is perpendicular to the rotation axis of the spool, under a function of centrifugal force produced by rotation of the spool. The ring-shaped braking member is provided on the reel main body so that the tip end portion of the brake lever can be brought into contact with the ring-shaped braking member.
