PURPOSE: To reduce inversion space and dead space to minimize a whole device in the workpiece inversion device which inverts the direction of a workpiece for a cylinder block.
CONSTITUTION: A workpiece inversion device is provided with an angle lever 2 whose intermediate section is fixed on a frame 1, whose one end is connected to an actuator 4, and in which a streak hole 7 which extends in the longitudinal axial direction is provided in the other end and a guide shaft 8 which protrudes in the frame 1 at a higher position than a pivotal point of the angle lever 2. It is further provided with an operation rod 9 which has a long hole 10 which extends in the longitudinal axial direction and in which a guide shaft 8 is inserted and engaged at one end and in which an engaging pin 11 which engages with the streak hole 7 of the angle lever 2 is provided at the other end and a workpiece inversion frame 12 like angle which is fixed in the central part of the operation rod 9 via a support shaft 13 and provided with a carry-in roller 14 and a carry-out roller 15 on planes which are orthogonal to each other.
