The present invention relates to a jig to assemble a flywheel and to elevate by a rigid clamping supporting both sides of the flywheel when mounting the flywheel to a crank shaft, capable of rotating the flywheel in an elevated state to enable easy work and simultaneously ensuring sight for the user. According to the present invention, the jig to clamp the flywheel having projected portions on a circumference on one side comprises: a clamping means which clamps the flywheel by contacting two sides of the flywheel in a thickness direction with at least a portion contacting an inner circumference of the projected portions, rotationally provided with a part contacting the projected portion, and a side surface of the flywheel to enable rotation of the flywheel in a clamped state; and an elevation means connected to the clamping means to elevate the flywheel. The clamping means comprises: a first rotation unit which contacts the inner circumference of the projected portions, rotating in the same direction as the flywheel by contacting the inner circumference of the projected portions during the rotation of the flywheel; a second rotation unit which supports an opposite side of the flywheel, rotating in a perpendicular direction to the rotation of the flywheel by contacting an other surface of the flywheel; and a gap adjusting unit to adjust a gap between the first and the second rotation units. |
