Claims

[Claims for Utility Model Registration] 1. A first rotating body having a fitting hole in the rotation axis, and a second rotating body provided concentrically with a space between the first rotating body and the first rotating body. A device for integrally rotatably connecting the first rotating body, which is fitted concentrically into and removably into the fitting hole of the first rotating body, and has a plurality of grooves formed at intervals in the circumferential direction. a hollow collet, which is rotatably provided integrally with the second rotating body and is slidably inserted concentrically into the collet, and expands the diameter of the collet by sliding in a predetermined direction. a tapered shaft that is slidably in contact with the inner circumferential surface of the collet via a tapered surface; a drive means for sliding in the predetermined direction; a plurality of key grooves formed at intervals in the circumferential direction on the outer circumferential surface of the tapered shaft at positions facing each of the split grooves; 1. A connecting device for connecting rotary bodies, comprising a key inserted into the collet and engaged with the collet at each slot. 2. A device for rotatably connecting a rod-shaped first rotating body and a second rotating body that is provided concentrically with an interval from the first rotating body; A hollow collet is slidably fitted concentrically to the first rotating body and has a plurality of grooves spaced apart from each other in the circumferential direction, and a hollow collet is rotatably provided integrally with the second rotating body. A hollow member is slidably fitted concentrically to the collet, and is in sliding contact with the outer circumferential surface of the collet via a tapered surface so as to reduce the diameter of the collet by sliding the collet in a predetermined direction. a tapered shaft; a driving means for sliding the collet in the predetermined direction so as to reduce the diameter of the collet and press it against the outer circumferential surface of the first rotary body; A plurality of key grooves are formed on the inner circumferential surface of the shaft at intervals in the circumferential direction, and a key is fitted into each key groove and engaged with the collet at the position of each split groove. Features: A connecting device between rotating bodies. 3. The width of the key groove is formed to be larger than the width of the split groove, and the width of the portion of the key that is fitted into the key groove is the width of the portion that is engaged with the collet at the position of the split groove. 3. A connecting device for connecting rotating bodies according to claim 1 or claim 2, characterized in that the connecting device is larger than the size of the rotating body.
