Abstract
Provided is a motion conversion device that can properly support a load acting axially on a planetary gear unevenly. A radius of a ring gear being a stationary internal gear is twice a radius of the planetary gear that rotates integrally with a crank member. A first planetary bearing and a second planetary bearing that support the planetary gear relative to a carrier are respectively disposed on one side and another side of an axial direction with respect to a planetary gear tooth section. A first carrier bearing and a second carrier bearing that support the carrier relative to the ring gear are respectively disposed on one side and another side of the axial direction with respect to a ring gear tooth section so as to respectively overlap, when viewed along a radial direction, movement trajectories of the first and second planetary bearings being generated when the planetary gear revolves.
