用トルクカム装置のシール構造。 A fixed sheave that rotates integrally with the shaft and a movable sheave that is movable in the axial and rotational directions relative to the shaft form a V-belt wrapping groove that can be expanded and contracted, and a thrust force corresponding to the torque is generated behind the movable sheave. In a V-belt continuously variable transmission equipped with a torque cam device that generates a It consists of a cam surface formed on the opposing surface of the torque cam flange and the cam member, and a cam roller arranged between both cam surfaces, and the torque cam flange has a first cylinder protruding from the cam roller that covers the outer periphery of the cam roller, and a movable cylinder. A second cylinder is arranged behind the sheave in sliding contact with the first cylinder via a seal member,
A seal structure for a torque cam device for a V-belt type continuously variable transmission, characterized in that a spring is disposed between the second cylinder and the cam member.
