A reduction gear W1 that is configured to reduce a rotation speed input to an input shaft 1, and output the reduced rotation speed from an output shaft, the reduction gear including: an inner trochoid 8 that has a wavy curved surface formed on an inner circumferential side surface thereof; an inner trochoid holder 9 that is designed to hold the inner trochoid 8; an outer trochoid 3 that has a wavy curved surface formed on an outer circumferential side surface thereof; a rotation restriction unit that is designed to restrict rotation of the outer trochoid 3 around an axis thereof; and an output pin 9 that is pinched between the outer circumferential side surface of the outer trochoid 3 and the inner circumferential side surface of the inner trochoid 8, in which the outer trochoid 3 receives eccentric input from the input shaft 1 and at the same time the rotation around the axis thereof is restricted by the rotation restriction unit, which makes the outer trochoid only revolve around an axis of rotation of the input shaft, the inner trochoid holder transmits eccentric input generated by the rotation of the input shaft 1 to the inner trochoid 8 to make the inner trochoid 8 revolve around the axis of rotation of the input shaft 1 and at the same time to make the inner trochoid 8 rotate around an axis thereof in the same direction as a direction of the rotation of the input shaft 1.
