ガイド軸7に移動自在に嵌挿された可動体である。Structure of a conventional example and its problems FIG. 1 shows a digital audio disc player using a conventional coupling device. In Fig. 1, 1 is a base;
Reference numerals 2 and 3 refer to walls provided in parallel at two locations on the base 1, 4 a feed motor fixed to one end of the base 1, 4a its output shaft, and 6 a bearing with both ends of the walls 2 and 3 (Fig. 6 is a connecting member that connects the output shaft 4a of the motor 4 and one end of the feed screw 6; T is the wall 2, 3;
A guide shaft 8 disposed parallel to the feed screw 6 in between has an optical pickup 9 in the center, has a pin 1o at one end to be inserted into the thread groove of the feed screw 6, and has a feed shinshiro and a guide shaft at both ends. It is a movable body that is movably inserted into the shaft 7.
上記構成において、モータ4はディスクの回転に応じて

ながら可動体8が送りネジ5の軸方向に直線的に移動さ
れ、光ピツクアップ9がディスクの半径方向に移動して
ディスクの情報を光学的に読みとる。In the above configuration, the motor 4 is rotated in accordance with the rotation of the disk, and rotates the feed screw 5 via the connecting member 6. As a result, the movable body 8 is moved linearly in the axial direction of the feed screw 5 while the pin 1o is guided by the thread groove of the feed screw 5, and the optical pickup 9 is moved in the radial direction of the disk to optically pick up information on the disk. Read it accurately.

発生することは避けられなかった。If such a connecting member e is used, it is possible to absorb the vibration of the output shaft 4a of the motor 4 to some extent as shown in FIG. 3(-), but it is inevitable that the output of the motor 4 will decrease. . In addition, misalignment between the output shaft 4a of the motor 4 and the feed screw 5 as shown in FIG. 3(b) cannot essentially be absorbed, and even in this case, a decrease in the output of the motor 4 can be avoided. I couldn't.

のである。Structure of the Invention The present invention fixes separate connecting members to the output shaft and rotating shaft of a motor, and loosely fits a protrusion provided on one of the two coupling members into a recess provided on the other, thereby reducing the gap between the protrusion and the recess. The gap absorbs the misalignment between the output shaft of the motor and the rotating shaft, allowing the motor to rotate smoothly and preventing the output from decreasing.
