Patent ID: 7469471

Claim:
A work-assembling auxiliary device including an engage means capable of being brought into engagement with a to-be-engaged means (h) provided in a crankshaft of an engine to transmit a rotational force of a drive means to said crankshaft of the engine through said engagement means and said to-be-engaged means, thereby spline-coupling a main shaft of a transmission to a torque converter integrally provided on an end of said crankshaft opposite from said to-be-engaged means, characterized in that said work-assembling auxiliary device comprises: an input shaft connected to said drive means, an output shaft having said engagement means, a coupling for connecting said output shaft to said input shaft, so that said output shaft can be moved radially in parallel to said input shaft, a first repulsively biasing means for biasing said output shaft, so that said output shaft is lined up with said input shaft 30 on a same axis, a second repulsively biasing means for biasing said engage means in a direction to engage said to-be-engaged means, and an engaging guide means provided on at least one of said engage means and said to-be-engaged means, said drive means causing the rotation of the input shaft through a predetermined angle and the stoppage of the input shaft for a predetermined time alternately and repeatedly.
