According to the present invention, provided is a fixed ball-type joint for a vehicle comprising: an outer race rotating by receiving the rotating power of an engine and having an outer race track formed on an inner surface in the lengthwise direction of the x-axis; an inner race installed inside the outer race and having an inner race track formed on an outer surface in the lengthwise direction of the x-axis; multiple balls for transmitting the rotating power of the outer race to the inner race; and a cage installed between the outer race and the inner race to restrict the multiple balls onto the x-axis and the y-axis and having windows with each ball inserted therein formed to support the balls. The outer race track is divided into a continuously engraved curved track and a linear track, wherein the radial center of the curved track is offset by distance ′f′ on the x-axis and is placed to be inclined at a first skew angle, and the linear track is placed to be inclined inward at a first taper angle with respect to the x-axis. The inner race track is divided into a continuously engraved curved track and a linear track, wherein the radial center of the curved track is offset by distance ′f′ on the x-axis, is placed to be inclined at a second skew angle and is placed to be symmetrical with the radial center of the curved track of the outer race track with the rotational center of the joint therebetween, and the linear track is placed to be inclined inward at a second taper angle with respect to the x-axis. |
