摘要： A spring leaf and an overrunning clutch provided with the same are provided. The spring leaf is made up of a support strip (3-1), a clamping strip (3-2), and a connection beam (3-3). The support strip (3-1) supports a needle roller in suspension. The connection beam (3-3) connects the support strip (3-1) with the clamping strip (3-2). The main body of the clamping strip (3-2) is a straight strip (3-2-1), either end of which is provided with a V-shaped bended part (3-2-2). The overrunning clutch is provided with a retainer, multiple needle rollers, and multiple spring leaves. Mounting grooves for the spring leaves are respectively disposed at positions, corresponding to each crossbeam, on outer end surfaces of a first and a second annular end edge at both ends of a window hole of the retainer. The bottom of the mounting groove for the spring leaf is V-shaped when cut along an axial direction of the retainer. An inner surface of the straight strip (3-2-1) of the clamping strip (3-2) of the spring leaf is matched with an outer surface of the crossbeam. An inner surface of the V-shaped bended part (3-2-2) of the clamping strip (3-2) is matched with a bottom surface of the mounting groove for the spring leaf. The technical problem of the potential displacement and detachment of the spring leaf during the reciprocation of the existing overrunning clutch at a high rotational speed and high frequency is solved by the invention.
