ロケツト。[Scope of Claim for Utility Model Registration] (1) A sprocket body having a through hole in the shaft center with a cross-sectional shape connecting points at unequal distances from the center of the shaft, and a shaft hole and a keyway in the shaft center. A sprocket having two boss members having the same cross-sectional shape as the through hole and fitted into the hole from both ends, and a connecting means for separably fixing the members, the inner periphery of the through hole The surface and the outer circumferential surface of the fitting portion of the boss member that slides into contact with the inner circumferential surface are formed so that the cross section including the axis has the same wedge shape, and the fitting portion of the boss member is formed between the surface of the shaft and the inner circumference of the through hole. A split type sprocket characterized in that the sprocket body is fixed to the shaft by driving the sprocket body from both ends into the gap between the sprocket and the surface. (2) Claim 1 is characterized in that a slit is formed in the fitting part of the boss member along a plane including the axis line, the length of which is approximately equal to the entire length of the fitting part from the wedge-shaped tip. Split type sprocket as described. (3) The split sprocket according to claim 2, wherein a plurality of slits are formed, and one of the slits is a slit that divides the keyway into two.
