  • Patent number: 10742087
    Abstract: A resin waterproof cover for covering an outside of a motor apparatus is comprising a cylindrical cap, a cap cover, a lead wire guide portion for inverting and leading out a power supply lead wire from inside of a motor case to the outside of the waterproof cover into a U shape, and cap engagement portions. The resin waterproof cover further comprises a first seal portion made of a photo-curable adhesive formed between the outer periphery near the bottom of the motor case, the other end of the cylindrical cap, and an end bracket of a reduction gear structure, a second seal portion made of a photo-curing adhesive formed on the lead wire guide portion, and a third seal portion made of a light curable adhesive formed between the periphery of one end of the cylindrical cap and the cap cover.
    Type: Grant

  • Patent number: 6909214
    Abstract: A small motor in a casing has a motor shaft, which has a worm outside the casing. A worm wheel is rotatably mounted to a housing for a reduction mechanism and meshes with the worm. The motor shaft is supported by radial bearings in the housing, and is supported at the bottom by a thrust bearing thereby simplifying the structure. Furthermore, a rotary disc is fixed to the motor shaft to rotate together with the motor shaft. An angle of rotation of the motor shaft is detected by a rotation detector via the rotary disc and converted to a digital signal by an electronic circuit.
