PURPOSE: To reduce an inter-affection between both members by maintaining a sprag free-wheel and radial roller bearing axially in an inter-middle space. CONSTITUTION: A free-wheel unit 1 comprising a sprag free-wheel 2 and a radial roller bearing 15 is assembled between a rotatingly driving member 13 and a rotatingly driven member 17. The sprag free-wheel 2 is formed of a plurality of sprags 4, retainers 10, and a trimming material 5. The radial roller bearing 15 is formed of a plurality of rolling elements 19 and a rim member 6, and the rolling elements 19 are disposed so that they are guided by one retainer 12 and surround the rotating driven member 17. The rim member 6 is disposed generally in the same manner as the trim member 5 of the sprag free-wheel 2. Then the rim members 5 and 6 are made to invade into a groove 8 inside the inter-middle space 14 so as to form an axial maintaining part 3 for the free-wheel unit 1. |
