PROBLEM TO BE SOLVED: To provide a press frame which can be easily transported, is free from production of casting defects, and has resistance to a press load, and with which press height can be reduced. SOLUTION: The press frame is constituted of a bed 3, a pair of right and left side frames 2, 2 erected at the upper face of the bed 3, a connection member 10 connecting the top ends of the pair of the right and left side frames 2, 2 to each other. The connection member 10 is constituted of a forward connection member 10A for connecting the forward portions at the upper ends of the pair of the right and left side frames 2, 2 to each other and the backward connection member 10B connecting the backward portions to each other. The forward connection member 10A is exerted with the tightening force along a back and forth direction between the upper ends of the pair of the right and left side frames 2, 2 and is connected to the upper end front of the pair of the right and left side frames 2, 2. The backward connection member 10B is exerted with the tightening force along the back and forth direction between the upper ends of the pair of the right and left side frames 2, 2 and is connected to the upper end back of the pair of the right and left side frames 2, 2.
