Motor apparatus with waterproof cover for vehicle

A motor apparatus with waterproof cover for a vehicle, comprising:

• a motor having a cup-shaped motor case, an end cover fixed to the opening portion of the motor case, and a rotating shaft held by a bottom portion of the motor case and the end cover;
• a reduction gear structure having a cup-shaped casing, an end bracket fixed to an opening portion of the casing, a reduction gear disposed inside the casing, an input shaft, and an output shaft, wherein the rotating shaft of the motor is the input shaft of the reduction gear structure, and the input shaft is coaxial with the output shaft;
• and
• a cup-shaped waterproof cover which is made of a transparent resin and is mounted on the outside of the motor case,
• wherein the end bracket of the reduction gear structure is fixed to the bottom portion of the motor case,
• wherein the cup-shaped waterproof cover comprises a cylindrical cap, a disk-shaped cap cover, a cap engagement portion, and a lead wire guide portion,
• wherein the cap engagement portion is provided on one end of the cylindrical cap and on the cap cover, and brings the cylindrical cap and the cap cover into mechanical engagement with each other,
• wherein the lead wire guide portion is formed between one end of the cylindrical cap and the cap cover, on a side opposed to the cap engagement portion across the center point of the cap cover, for inverting and leading out a motor power supply lead wire and a power supply connection connector into a U shape from the motor to the outside of the waterproof cover, and
• wherein the cylindrical cap is loosely fitted to the motor case, the motor apparatus further comprising:
• a first seal portion made of a photocurable resin adhesive which is formed in the vicinity of a contact surface of the motor case with the reduction gear structure and fixes the cylindrical cap to the motor case and the end bracket;
• a second seal portion made of a photocurable resin adhesive at the lead wire guide portion for fixing a part of the power supply lead wire to the lead wire guide portion;
• and
• a third seal portion made of a photocurable resin adhesive between the periphery of the one end of the cylindrical cap and the cap cover for fixing the cylindrical cap and the cap cover to each other.
