PURPOSE:To enable the positioning of interlocking gear wheels to be easily carried out by forming a recessed and a projected part for positioning so as to restrict the respective interlocking position, on respective engaging teeth of a pair of interlocking gear wheels. CONSTITUTION:On respective interlocking gear wheels 1 and 2 in which engaging gear teeth 3 and 4 are formed in a prescribed range of angles, a recessed tooth 5 and a projected tooth 6, which are formed on one end side in the axial direction of respective engaging gears 3 and 4 so as to be adjacent, are formed. Thus, since the interlocking position of both interlocking gear wheels 1 and 2 can be accurately set, the assembling work can be very easily carried out.
