PROBLEM TO BE SOLVED: To provide a dynamic balancing machine for a crankshaft equipped with a pressing device capable of pressing surely the crankshaft at an unbalance measuring time so that the crankshaft to be subjected to unbalance measurement can be rotated excellently. SOLUTION: This shaft pressing device is constituted of a rotating shaft 29; an eccentric shaft 32 provided on one end side of the rotating shaft 29, which is parallel to the rotating shaft 29 and eccentric to the rotating shaft 29; a link mechanism 31 for connecting one end side of the rotating shaft 29 to one end side of the eccentric shaft 32, and rotating the eccentric shaft 32 following rotation of the rotating shaft 29; a pressing roller 35 provided on the other end side of the eccentric shaft 32, to be displaced following rotation of the eccentric shaft 32; and an air cylinder 36 for rotating the rotating shaft 29 connected to the other end of the rotating shaft 29. Hereby, one end side shaft of the crankshaft can be pressed excellently without interfering with a hook drive mechanism. COPYRIGHT: (C)2007,JPO&INPIT
