To provide a small-sized reduction gear which can lock an input from an output side, and a geared motor.SOLUTION: A lock part has: an input body having an input plate part, and rotating around a center axial line accompanying the revolution-rotation of a planetary gear; an output body having an output plate part opposing the input plate part in an axial direction; a connecting part for connecting the input body and the output body with a clearance in a peripheral direction; and a plate spring. A recess having a first inside face oriented to one side in the peripheral direction and a second inside face oriented to the other side in the peripheral direction is formed at an outer edge of the input plate part. A protrusion having a first outside face oriented to one seat in the peripheral direction and a second outside face oriented to the other side in the peripheral direction is formed at an outer edge of the output plate part. The plate spring has a circular-arc shaped circular arc part extending along an internal peripheral face of a case, a first claw part located at an end part of the circular arc part at one side in the peripheral direction, and a second claw part located at an end part of the circular arc part at the other side in the peripheral direction.
