To provide a propeller shaft which is largely increased in a slide amount.SOLUTION: A propeller shaft 1 comprises: a first shaft member 2 having a first end part 2a and a second end part 2b being both end parts of the first shaft member 2 in a rotation axial line P direction; a first constant velocity joint 3 having a first inner ring member and a first outer ring member 34; and a second constant velocity joint 4 having a second inner ring member and a second outer ring member 44. When the first shaft member moves toward the first end part from the second end part in the rotation axial line direction, a distance in which a second ball 42 can move toward an edge part 44a1 of a second race groove 44a is longer than a distance in which a bottom part 34b of the first outer ring can move toward the first end part of the first shaft member, and when the first shaft member moves toward the second end part from the first end part, a distance in which a first ball 32 can move toward an edge part 34a1 of a first race groove 34a is longer than a distance in which the second end part can move toward a bottom part of the second outer ring member.SELECTED DRAWING: Figure 1
【課題】摺動量を大幅に増加させたプロペラシャフトを提供する。【解決手段】プロペラシャフト1は、第1軸部材2の回転軸線Pの方向における両端部である第1端部2aと第2端部2bを有する第1軸部材と、第1内輪部材と第1外輪部材34を有した第1等速ジョイント3と、第2内輪部材と、第2外輪部材44と、を有した第2等速ジョイント4と、を備え、回転軸線の方向において、第1軸部材が第2端部から第1端部に向かって移動するときに、第1外輪部材の底部34bが第1軸部材の第1端部に向かって移動可能な距離よりも第2ボール42が第2レース溝44aの縁部44a1に向かって移動可能な距離の方が長く、かつ、第1軸部材が第1端部から第2端部に向かって移動するときに、第2端部が第2外輪部材の底部に向かって移動可能な距離よりも第1ボール32が第1レース溝34aの縁部34a1に向かって移動可能な距離の方が長いことを特徴とする。【選択図】図1
