In a crank press, a slide is mounted on a crankshaft, reciprocates vertically to a certain extent due to rotating of the crankshaft, and presses a work piece to a die so as to form the required product. The crank press of the present invention comprises a slide S which has V-shaped depressed portions 7 to reciprocate vertically between two frames (2), and guides (G1, G2) whose a surface are protruded correspondingly to depressed portions (7), so that the slide is moved up and down along the guides in the frames without clearance. |
