PURPOSE: A fixed type constant velocity joint is provided to facilitate to manufacture by forging due to forming the input and output gradient of a mold by the trace of a ball of a zeppa type constant velocity joint which moves to non-circular. CONSTITUTION: A fixed type constant velocity joint comprises an outer rim(110) wherein ball guide grooves(110a) are formed on the inner surface of the outer rim along the circumferential direction to the axial direction, an inner rim(120) wherein ball guide grooves(120a) are formed on the outer surface of the inner rim in order to face to the ball guide grooves of the outer rim along the circumferential direction to the axial direction, a torque transferring ball(130) which is arranged so that an operating angle is guided with the ball guide groove of the outer rim and the ball guide groove of the inner rim, and a cage(140) which includes a pocket(140a) supporting the torque transferring ball and is installed between the outer rim and the inner rim. The center trace of the ball guide groove of the outer rim forms a straight line from a point meeting with the cross sectional area of a shaft to the opening direction of the outer rim. The center trace of the ball guide groove of the inner rim forms a straight line from a point meeting with the cross sectional area of a shaft to the inside direction of the outer rim.
