Abstract: A motor includes a motor body, a pin, a core, and an input cam. The motor body includes a housing and an output shaft. The pin is arranged in the output shaft to extend in a direction orthogonal to a rotation axis of the output shaft. The core is pivotally supported by the pin and rotates coaxially with the output shaft. The input cam is annular and surrounds an outer circumference of the core. The input cam rotates integrally with the core. An end surface of the core closer to the housing includes a first deviated surface. The core includes an insertion portion into which the pin is inserted. When a center axis of the core is coaxial to the rotation axis of the output shaft, the first deviated surface is located at a position farther from the housing than the insertion portion.

Abstract: A planet bearing has a single row of spherical rolling elements between an outer wheel and an inner wheel. A planet gear is supported by the outer wheel from a radially inner side. A planet carrier supports the inner wheel from a radially inner side. An elastic component is interposed between the inner wheel and the planet carrier. A driving rotor or a driven rotor has a thrust bearing part that supports the planet gear from one side in the axial direction. The outer wheel is in contact with the spherical rolling element at a rolling contact point and defines a contact angle on the one side in the axial direction.

Abstract: In a definition cross-section of a planet gear located on an eccentric side in a radial direction relative to a driving rotor and a driven rotor, an imaginary straight line is defined by connecting a center of a planet side outer arc part that configures a raceway groove of a planet outer wheel on the eccentric side to a center of a solar side outer arc part that configures a raceway groove of a solar outer wheel on an opposite side opposite from the eccentric side. A planet side inner arc part of a planet inner wheel and a solar side inner arc part of a solar inner wheel are located on the imaginary straight line in the definition cross-section.

Abstract: A planetary carrier supports a geared rotor from an inside in a radial direction, and receives a radial load in a first region, which is offset to one end from a center position in an axial direction. A ball bearing roller supports the planetary carrier from an outside in the radial direction in a second region, which is offset to an other end from the center position. The ball bearing roller is a single-row ball bearing roller that has an outer ring supported by a drive rotor, an inner ring which supports the planetary carrier, and a plurality of rolling elements which are rotatably installed in a single row to be in contact with and between the outer and the inner rings. The geared rotor is tilted relative to the axial direction, and contacts a driven rotor in the axial direction. An angle of the geared rotor relative to the axial direction is set to be smaller than a maximum allowable angle at which the inner ring is allowed to be tilted relative to the axial direction.
