PROBLEM TO BE SOLVED: To provide a rotary jig for assembly which can easily performs an operation for aligning each fastening part of a first rotary body and a second rotary body with a fastening window, and a fastening operation for each fastening part without use of a device such as a motor for electrical control.SOLUTION: A rotary jig 1 for assembly is used for assembling a drive plate 73 of a crank shaft built in an engine 7 with a connection plate 82 built in a torque converter by plural fastening parts A which are arranged in a circumferential direction C at intervals of a predetermined angle &thetas;. The rotary jig 1 for assembly includes: a jig body part 2; a rotary shaft part 3 which is so engaged with the crank shaft as to have a rotation center coincident with that of the crank shaft; a ratchet mechanism 4 which successively restricts an amount of rotation of the rotary shaft part 3 in a normal direction C1, and on the other hand, prevents rotation of the rotary shaft part 3 in a reverse direction C2; and plural handle parts 5 which are provided on an outer periphery of the rotary shaft part 3 at intervals of a predetermined angle &thetas;. |
