In the above embodiment, the mounting positions of the rod expanding / contracting mechanism 2 and the locking hole member 4 can be changed with respect to the machine frame 1. At least one of them may be integrally fixed to a predetermined position of the machine casing 1. Also, the locking hole member 4 is composed of left and right divided pieces 4a, 4a, and these divided pieces 4a, 4a are configured to be brought into contact with and separated from each other via a screw mechanism. Alternatively, a large or small locking hole member having a circular hole through which the shaft B can be inserted or a U-shaped hole whose upper end is opened may be replaceably fixed to the central portion in the width direction of the machine frame 1.

むことができるものである。As described above, according to the present invention, the locking hole member is fixed to the other end side of the machine frame so as to face the axial center of the rod mounted on one end side of the machine frame so as to move back and forth. Since the bearing is received on the rod-side facing surface of the locking hole member, the shaft is disposed between the locking hole member and the rod, and then one end surface of the shaft is fixed by the rod. By pressing, the other end of the shaft can be reliably and efficiently fitted into the bearing.

できるものである。Further, the bearing attaching / detaching device of the present invention includes a rod disposed on one end side of the machine frame so as to be able to move forward and backward, a locking hole member fixed on the other end side, and a support member for supporting the bearing mounting shaft. Since it has a simple structure consisting of and, it is easy to carry, operate and handle, and even if there is only one worker, it is possible to attach and detach the bearings efficiently. In addition, the work can be performed safely, and even if the shaft is equipped with a motor coil or the like, the bearing can be attached / detached to / from a predetermined position of the shaft end in the mounting form.
