A ball spline includes a spline shaft, an outer sleeve, and two circulation elements. The outer sleeve is slidably sleeved on the spline shaft to form a load channel therebetween for installation of balls, and has an oil guide channel inside. The circulation elements are mounted to two outer end surfaces of the outer sleeve and each has an oil filling hole, an oil storage tank communicating with the oil filling hole, the load channel, and the oil guide channel, and an oil guide portion disposed in the oil storage tank and corresponding to the oil filling hole and protruding towards the oil guide channel. Thus, after injecting lubricant into the oil filling hole of one of the circulation elements, the lubricant lubricates the balls on both sides by means of the oil guide portion and the oil guide channel, thus enhancing the lubrication effect.
