The sprags 11 are prevented from hitting the side plate 2 on the other end side in the axial direction by a protrusion part 5c provided to the outer ring 5. According to this structure, because the sprags 11 do not hit the side plate 2, the range of the oil groove 33 in the surface on the sprag 11 side of the side plate 2 can be set wide. If the oil groove 33 is formed over the entire length in the radial direction of the side plate 2, it can contribute to prevention of wear between the side plate 2 and the inner ring 4.  <P>COPYRIGHT: (C)2009,JPO&INPIT
