を特徴とするフリーホイール。 A freewheel in which a cylindrical driving body having a sprocket is freely rotatably supported around the outside of the cylindrical driven body by a ball bearing, and a one-way rotation transmission mechanism is provided between the driving body and the driven body. An extension part extending axially outward from a screwing position where the ball pusher of the ball bearing is screwed is formed at the axially outer end of the driven body, and the outer periphery of the extension part and the extension part A first seal body having an annular groove is attached to one side of the inner periphery of the driving body facing the inner periphery of the driving body, and the other side has an annular fitting part that fits loosely into the annular groove of the first seal body. Attach the second seal body and
A freewheel characterized in that a second seal body fills an annular space between the outer periphery of the extension part and the inner periphery of the driving body.
