Claims

[Scope of utility model registration request]

(1) In a friction transmission device comprising a friction transmission body such as a roller, and an input shaft and a power shaft connected via the friction transmission body, the traction of the transfer surface of the friction transmission body is increased using traction-increasing oil. A friction transmission device, characterized in that a groove for storing and retaining traction-enhancing oil is formed on the transfer surface of the friction transmission body.

(2) The friction transmission device according to claim 1, wherein the groove for storing and holding the traction-enhancing oil includes a traction-increasing oil-impregnated body built into the friction transmission body.
