Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a motor capable of improving the durability and strength of a worm and a counter gear.
SOLUTION: This motor 10 comprises a pair of worms 15, 15' formed by making twisting directions of screws in reverse directions to each other near one end of a motor shaft 14; a pair of the counter gears 30, 30 which include a large-diameter gear 31 and a small-diameter gear 35, face each other with the motor shaft 14 sandwiched, and engaged with each large-diameter gear 31 in each worm; and an output gear 40 engaged with the small-diameter gear 35 of each counter gear. The large-diameter gear 31 of each counter gear are formed out of synthetic resin, the small-diameter gear 35 is formed out of metal, teeth 32 engaged with each worm are formed on the outer periphery of the large-diameter gear 31, an internal spline 33 is formed on the outer periphery of the large-diameter gear 31, and teeth 36 engaged with the output gear 40 and an external spline 37 engaged with the internal spline 33 of the large-diameter gear are integrally formed in the axial direction on the outer periphery of the small-diameter gear 35.
