In the present invention, a water-proof cover (30) is provided at a position on the open part side of a pressure ring (26) of a transmission shaft (which is a short shaft (8) in this case), and the water-proof cover (30) is provided with an open part extending so as to approach the open part of the pressure ring (26). Furthermore, the waterproof cover (30) is fixed at a position on the open part side of the compression ring (26) of the short shaft (8), and the open part of the waterproof cover (30) extends in a manner of approaching the open part of the compression ring (26), so that even if muddy water and the like fly from the open part side of the compression ring (26) in the inclined direction, the possibility that the muddy water and the like enter the open part of the compression ring (26) can be inhibited, and the service life of the compression ring (26) can be prolonged. As a result, a phenomenon in which muddy water or the like intrudes into the center bearing (19) is less likely to occur.
在本发明中,在传动轴(在此为短轴(8))的压环(26)的开放部侧的位置,设置有隔水罩(30),该隔水罩(30)具备以接近压环(26)的开放部的方式延伸的开放部。而且,隔水罩(30)固定在短轴(8)的压环(26)的开放部侧的位置,隔水罩(30)的开放部以接近压环(26)的开放部的方式延伸,因此,即使泥水等从压环(26)的开放部侧沿倾斜方向飞舞来,也能够抑制泥水等侵入到压环(26)的开放部的可能性,结果是能够使泥水等侵入到中心轴承(19)的内部的现象难以发生。
