<p>PURPOSE:To provide a wet type multi-plate tightening device which is able to reduce the select lag even when a clearance between plates is set large so as to reduce a drap torque. CONSTITUTION:A group of plates is divided into two toward a piston member via a push member 13, and an intermediate plate 10. Or otherwise, an elastic member is placed between respective primary plates, and elastic modulus of at least one plate is made larger than that of others, and during the initial tightening stage, torque transmission is thus made by a part 11 of the group of plates.</p> |
