Wiper apparatus and manufacturing method thereof

A wiper apparatus having a wiper motor which swings and drives a wiper member provided on a windshield, and wiping deposits on the windshield, the wiper apparatus comprising:

• a yoke, inside which magnets are fixed so as to be arranged oppositely to each other and which forms the wiper motor;
• an armature shaft rotatably provided between the magnets;
• a gear case connected to the yoke and forming the wiper motor;
• a speed-reduction mechanism rotatably provided in the gear case and reducing speed of rotation of the armature shaft;
• an output shaft, whose base end side is fixed to the speed-reduction mechanism and whose tip side extends outside the gear case;
• a rotational-position detecting member provided in the gear case and detecting a rotational position of the output shaft with respect to the gear case;
• a link plate, whose base end side is fixed on the tip side of the output shaft at a prescribed position with respect to a rotational direction of the output shaft;
• and
• a motor bracket provided between the wiper motor and the link plate, the wiper motor being mounted onto one side surface of the motor bracket, and the motor bracket having a through-hole through which the output shaft passes toward the other side surface of the motor bracket,
• wherein a diameter dimension of the through-hole is set to a diameter dimension of allowing a tip side of the link plate to pass through the through-hole in a state where the link plate is inclined with respect to the motor bracket.
