PROBLEM TO BE SOLVED: To assure direct engagement of two gears. SOLUTION: A first gear 300 and a second gear 350 are arranged to be engaged with each other, the first gear 300 includes teeth 310 constituting a part of an outer periphery, the second gear 350 includes teeth 360 constituting a part of an outer periphery, a tooth tip land 312 from a first end part 314 to a second end part 316, of the teeth 310 of the first gear is inclined and curved, a tooth tip land 362 from a first end part 364 to a second end part 366, of the teeth 360 of the second gear is also inclined and curved, and a center of radius of each of the tooth tip lands 312, 316 is not agreed with a center of a main body, thus the engagement of the tooth tip lands is prevented, and the gears can be surely directly engaged with each other.
