For press fitting a pin member into aligned holes of works, a press fitting tool is provided, which comprises a pin diameter reducing device that reduces at least a leading end of the pin member to a given diameter by applying an external force to the pin member. The given diameter is smaller than that of the aligned holes. The press fitting tool further comprises an actuating device that thrusts the pin member in a direction to insert the diametrically reduced leading end of the pin member into an inlet portion of the aligned holes without inducing abutment of the diametrically reduced leading end of the pin member with a peripheral edge of the inlet portion of the aligned holes.
