The vehicle motion converter

PROBLEM TO BE SOLVED: To provide a motion conversion device for a vehicle which is further reducible in a size of the device as a whole.SOLUTION: A motion conversion device for a vehicle comprises: a ring gear 18 formed at an inner tooth gear 18c; a gear 17 rotationally driven around a first axial line O1 which is coaxial with the inner tooth gear 18c; and a planetary gear 21 in which an outer tooth gear 21b engaged with the inner tooth pin 18c and an output pin 23 are arranged, and the gear 17 is pivoted around a second axial line O2 which is decentered to the first axial line O1, and which revolves along the inner tooth gear 18c while rotating around the second axial line O2 so that the output pin 23 linearly moves.SELECTED DRAWING: Figure 1
