Abstract

See full text

In a brushless wiper motor, a rotor (33) is rotatably provided inside a stator (32) provided with a coil (32b), one end side of a rotation shaft (34) in the axial direction is fixed to the axial center of the rotor (33), a worm (35) is provided on the other end side of the rotation shaft (34) in the axial direction, the first and second bearings (36, 37) are respectively provided on one end side of the rotation shaft (34) in the axial direction and the other end side of the rotation shaft (34) in the axial direction than the worm (35) of the rotation shaft (34), the rotation shaft (34) is rotatably supported by only the first and second bearings (36, 37), and with the position of the first bearing (36) being defined as a reference position, a length thereof in the axial direction to the second bearing (37) is longer than a length thereof in the axial direction to the rotor (33). Since a commutator and other parts are not provided on a free end side of the rotation shaft (34), it is possible to provide a brushless wiper motor reduced in length of the rotation shaft (34), and reduced in inertial mass of the free end side of the rotation shaft (34).
