PROBLEM TO BE SOLVED: To efficiently compress a bale by protruding a bale restoration preventing pawl on the back face of a compression chamber to compress the ball efficiently, then connect an extrusion member with a door by the operation outside the compressor chamber and connect the bale with the door to extrude the same forward the compressor chamber. SOLUTION: An extrusion plate 14 is disposed on the back face side of a compressor chamber 2 and connected with a rod 19 through a stay 15 and a pipe 24 is slidably inserted in the rod 19 and set rotatably in the vicinity of a hinge section 18 of a large door 3. A hooking pawl 27 is rotatably supported and a foot-operated pedal 30 is provided outside the large door 3. When the ball is taken out, the hooking pawl 27 is rotated by the cam section 32 of the foot-operated pedal 30 and hooked it on the front end of the pipe 24, and the rod 19 is connected with the large door 3. In the above state, the large door 3 is opened and the rod 19 is drawn out and the bale is drawn forward the compressor chamber 2 by an extrusion plate 14 and removed from a rotation preventing pawl 13.
