A clutch apparatus comprising: a flywheel; a pressure plate arranged so as to face the flywheel; a clutch disc provided between the flywheel and the pressure plate; a clutch cover rotated together with the flywheel as a unit; a variable lever ratio mechanism provided within the clutch cover and having a force input portion (21a, 25a), to which an operation load is inputted, a force output portion (21c, 25c) at which the variable lever ratio mechanism presses the pressure plate towards the flywheel, and a lever (21, 25), whose lever ratio is set to be variable; and a biasing member biasing the variable lever ratio mechanism so that the variable lever ratio mechanism presses the pressure plate towards the flywheel at the force output point (21 c, 25c), wherein the variable lever ratio mechanism includes a first release lever having a force input portion, to which the operation load is inputted, a fulcrum portion, at which the first release lever is pivotally retained by the clutch cover, and a force output portion, at which the first release lever presses the pressure plate towards the flywheel by a biasing force of the biasing member, and a second release lever having a force input portion, at which an operation load from a release bearing is inputted, a fulcrum portion, at which the second release lever is pivotally retained by the clutch cover, and a force output portion, at which the second release lever presses the force input portion of the first release lever in a direction against the biasing force of the biasing member, and the second release lever is formed in a shape by which a contact position between the force input portion of the first release lever (21, 31) and the force output portion of the second release lever is displaced in a radially outer direction as the second release lever (25, 35) inclines towards the first release lever (21, 31). a flywheel; a pressure plate arranged so as to face the flywheel; a clutch disc provided between the flywheel and the pressure plate; a clutch cover rotated together with the flywheel as a unit; a variable lever ratio mechanism provided within the clutch cover and having a force input portion (21a, 25a), to which an operation load is inputted, a force output portion (21c, 25c) at which the variable lever ratio mechanism presses the pressure plate towards the flywheel, and a lever (21, 25), whose lever ratio is set to be variable; and a biasing member biasing the variable lever ratio mechanism so that the variable lever ratio mechanism presses the pressure plate towards the flywheel at the force output point (21 c, 25c), wherein the variable lever ratio mechanism includes a first release lever having a force input portion, to which the operation load is inputted, a fulcrum portion, at which the first release lever is pivotally retained by the clutch cover, and a force output portion, at which the first release lever presses the pressure plate towards the flywheel by a biasing force of the biasing member, and a second release lever having a force input portion, at which an operation load from a release bearing is inputted, a fulcrum portion, at which the second release lever is pivotally retained by the clutch cover, and a force output portion, at which the second release lever presses the force input portion of the first release lever in a direction against the biasing force of the biasing member, and the second release lever is formed in a shape by which a contact position between the force input portion of the first release lever (21, 31) and the force output portion of the second release lever is displaced in a radially outer direction as the second release lever (25, 35) inclines towards the first release lever (21, 31).
