Abstract

In a torque transmission apparatus 1, an oil seal 7 is placed at an outer periphery of a clutch 6 in its diameter direction. The clutch 6 has an outer 6a, an inner 6b, and a link member 6c. A lip part 7a of the oil seal 7 slides on the outer periphery of the outer 6a fixed to a primary rotary body 3. A bearing 4 placed at the inner periphery of the clutch 6 in the diameter direction is a ball bearing with a seal. In particular, a filling ratio of a lubricant with which a filling space formed between the bearing 4 and the oil seal 7 is filled is not more than 60 %. When an engine rotates, this structure suppresses the inner pressure of the oil seal 7 from increasing and a torque loss from increasing. The above structure decreases the fuel consumption of the engine.
