PURPOSE:To permit the arbitrary revolution dividing of a magazine body by shortening the tool replacement cycle by forming an inclined surface continuous to the outer peripheral surface of a supporting body by an engaging groove in the revolution dividing direction of the supporting body at the position corresponding to the engaging member at the advance edge of the magazine body. CONSTITUTION:An inclined surface 38 continuous to the outer peripheral surface of a supporting body 22 towards the revolution dividing direction of a magazine body 24 from the bottom surface of each engaging groove 35 is formed at the position corresponding to an engaging shaft 36, when the magazine body 24 is at the advance edge position. Therefore, at the advance edge position of the magazine body 24, the engaging shaft 36 overrides the inclined surface 38 against the springy force of a spring 37, and the revolution only in one direction of the magazine body 24 is permitted. Therefore, the advance/retreat movement and revolution dividing movement of the magazine body 24 are controlled in sequence, and the tool replacing cycle is shortened, and the arbitrary revolution dividing of the magazine body 24 can be carried out. |
