あった。As described above, there is a conventional method of rotating two members by connecting shafts. In either method, the dimensional accuracy of the two members and the stepped male screw or the shaft, or It is known that there is a cylinder without male threads, or one with a horizontal hole in the cylinder and fixing with a crack pin, or one with the tip of the cylinder protruding from the back of one member and caulking. It is necessary to accurately machine the dimensional accuracy, and a stepped male screw is made longer than the back of the member so that a female nut provided on the member is added with a threaded nut and tightened with a double nut. There is also a method of providing a stepped male screw and a counter-rotating female screw at the center of the male screw, and screwing in the male screw that mates with the female screw to prevent loosening of the stepped male screw. When friction is generated between the shaft and the member when it is applied, the loosening of the fixation between the male screw and the stepped male screw occurs as a phenomenon when the nut or the stepped male screw tip is attached to the female screw of the counter rotation. The phenomenon is that when the two members reciprocally rotate in the tightening direction, strong rotational friction occurs in the stepped male screw, causing a nut or a counter-rotating male screw and a stepped male screw attached to the center of the stepped male screw. The friction is loosened, and when the member is further rotated in the reverse direction, the stepped male screw part rotates in the direction of loosening. When the reciprocating rotations of the two members overlap, the installed intervals gradually increase, and in the worst case, the shaft Occasionally there was a dropout. In addition, since the shaft and the two members may rub against each other after being used for a long period of time, it may not be possible to adjust the play, and it may be necessary to replace the parts.

A rotating member provided with a cylindrical fitting hole for fitting the male screw to be fitted thereinto with the outer diameter of the cylindrical portion of the shaft member, and a fitting hole for fitting with two or more contact surfaces for preventing rotation of the shaft member. A shaft fixing member provided with a female screw to be fitted with the male screw,
The shaft member is inserted into a cylindrical fitting hole that substantially fits the outer diameter of the cylindrical portion of the shaft member of the rotating member, and further, two or more contact surfaces for preventing the shaft member from rotating and two or more surfaces for the shaft fixing member. It is fitted into the fitting hole that fits with the contact surface, and is attached.Furthermore, the male screw is passed through the through hole provided in the substantially central portion of the shaft member and screwed into the female screw of the shaft fixing member to attach the rotating member and the shaft fixing member. It can be mounted and rotated with a shaft member. (There is no contact between the rotating member and the male screw, the shaft member and the shaft fixing member are slidably integrated with the male screw, and the rotary contact relationship is that of the rotating member and the shaft member. Therefore, the rotational friction due to the reciprocating rotation between the rotating member and the shaft fixing member is not directly transmitted to the male screw, and the loosening of the male screw due to the rotating friction between the rotating member and the shaft fixing member does not occur at all. To fix the tip of the male screw It can be fixed more strongly by protruding from the surface opposite to the mounting surface of the fixing member, screwing the nut into the male screw, and making it a double nut with the female screw of the shaft fixing member and fixing it. It is also possible to use the crimping method of No. 2 in combination with a shaft member having two or more contact surfaces to prevent the rotational friction between the rotating member and the shaft fixing member from being directly transmitted to the stepped cylinder of the above-mentioned two methods to prevent rotational loosening. In addition, the shaft mounting interval can be easily adjusted with a male screw.

である。The rotating member and the shaft fixing member are screwed and mounted by fitting the two or more contact surfaces of the shaft member with the fitting holes of the shaft fixing member (at this time, the shaft member is attached to the base axis of the shaft member). It is slidable in the axial direction, and the shaft member and the shaft fixing member can be integrated. In addition, the rotation of the male screw and the shaft member are independent, and the loosening of the male screw due to friction between the rotating member and the shaft member is prevented. In addition, the fixing force can be maintained semi-permanently, the lightness and weight of the rotation can be freely adjusted by the tightening of the male screw, and the backlash due to long-term use can be easily moved and adjusted.
