PROBLEM TO BE SOLVED: To solve the problem that a composite noise and vibration are generated when adopting, as an apparatus for moving a vehicle seat, a conventional reduction gear comprising: an input shaft having a cog section being provided in a casing; a gear having an outer cog section that fits to a cog section in an input shaft; a washer being provided at both the boss sections of the gear; and an output shaft having a cog section that fits to the inner cog section of the gear being extended to the outside of the casing that penetrates the gear and the washer. SOLUTION: The reduction gear comprises: an input shaft having the cog section provided in the casing of the reduction gear; the gear having the outer cog section fitted to the cog section of the input shaft and a first locking section such as a waveform on the side of a shoulder section; a spring washer having a locking section having a second locking section such as a projecting piece provided at both the boss sections of the gear; and the output shaft having the cog section fitted to the inner cog section of the gear extending to the outside of the casing that penetrates the spring washer having the gear and the locking section. The first and second locking sections can be brought into contact each other, thus reducing noise and/or vibration and securing silence in a vehicle and the smooth movement of the seat.
