<P>PROBLEM TO BE SOLVED: To utilize rollers for an excitation body bearing so as to prevent skew and reduce loss of transmission torque. <P>SOLUTION: A deflection engagement type gear device 100 is equipped with: an excitation body 104; an external gear 120; excitation body bearing 110; an annulus gear 130A for deceleration; and an annulus gear 130B for output. While a gap Gp is provided whose size is increased as it extends toward the end part in the axial direction O of rollers 116A, 116B, between the rollers 116A, 116B prior to incorporation of an excitation body bearing 110 into the excitation body 104, and outer races 118A, 118B, whereas the size of the gap Gp is made to be equal to or greater than the amount of deformation of the outer races 118A, 118B under the state of the excitation body bearing 110 being incorporated in the excitation body 104. <P>COPYRIGHT: (C)2013,JPO&INPIT |
