摘要： A wiper blade wipes over a predetermined range of a front windshield in response to rotation of a wiper motor in a forward and reverse directions. The wiper blade operates in a wiping range between a predetermined upper reversing position and a predetermined lower reversing position. An upper pre-reversing position is defined inside of the upper reversing position, and a lower pre-reversing position is defined inside of the lower reversing position. A rotation sensor produces pulse signals in response to the rotation of the wiper motor. A CPU counts the pulse signals produced from the rotation sensor when a position detection sensor detects an arrival of the wiper blade at the pre-reversing position. The CPU produces a control signal to a drive circuit and reverses the direction of the drive current of the wiper motor to reverse the rotation of the wiper motor, when the pulse count value reaches a predetermined value.

摘要： Brush holding device includes a brush, a brush holder, a torsion spring and a support pin. The torsion spring applies side pressure to the brush by spring force exerted around the support pin and also temporarily hold the brush in the brush holder. When the temporarily held state of the brush holder is relieved, the spring force of the torsion spring urges the brush toward a commutator.

摘要： Each brush holder is formed by bending a holder material made of a metal plate, so that the brush holder is shaped into a generally rectangular tubular body, which includes opposed first and second lateral walls, a top wall and a base wall. A base plate includes holder limiting grooves. Each brush holder is received in a corresponding one of the limiting grooves. The limiting groove limits an increase in a space between the first lateral wall and the second lateral wall of the corresponding brush holder. Furthermore, each brush is received in a corresponding one of the brush holders in a slidable manner in a sliding direction toward and away from a commutator of a motor.

摘要： A wiper motor has brushes slidable in contact with a commutator, choke coils connected in series with the brushes, and a circuit breaker for preventing burn-out caused by excessively high current. The circuit breaker is disposed in the vicinity of the choke coils and operates based on heat generated by the choke coils.

摘要： A spindle and a position-limiting ridge protrude from an inner surface of a cover to rotatably support a follower made of an electrically conductive metal plate. A cylindrical engaging portion of the follower slidably engages the spindle. A toothed washer is fitted around the spindle to clamp a contact portion of the follower between the position-limiting ridge and the toothed washer in a rotatable manner. A switching pattern is provided in the inner surface of the cover. Contact terminals that engage and disengage with the switching pattern based on rotation of the follower are integrally formed in the follower. An engaging hole penetrates through the follower. An engaging protrusion on a carrier is received within the engaging hole. The follower is rotated through engagement between the engaging protrusion and the engaging hole when the carrier rotates in a forward rotational direction.

摘要： An electric noise suppressor for a direct current motor comprises a grommet, a choke coil and an electrical terminal. The grommet has an accommodating portion for accommodating the choke coil, an engaging portion for being engaged with a brush holding board of the motor, and a holding portion for holding the terminal. A pair of supporting portions for supporting a pigtail connector are formed to symmetrically protrude from an upper peripheral portion of the accommodating portion. Therefore, the terminal and the pigtail connector are disposed outside the accommodating portion of the grommet, thereby enabling inductance of the choke coil to increase. Further, the pigtail connector, the choke coil and the terminal are restricted from moving and chattering. As a result, the electrical noise suppressor requires less mounting space and is highly reliable.
