    摘要: A coupling unit includes two constant velocity joints arranged in series in the shaft direction. The coupling unit couples a driven shaft and a drive shaft. Each constant velocity joint includes a ball non-retaining member and a ball retaining member. The ball non-retaining member has an annular space with one opened end and a plurality of track grooves extending in the shaft direction on an external wall surface of the annular space at a constant interval in a circumferential direction. The ball retaining member has a portion that engages with the annular space of the ball non-retaining member, and that retains a ball that slides along each of the track grooves formed in the ball non-retaining member.
