PROBLEM TO BE SOLVED: To miniaturize the configuration of a power transmission mechanism used for a heat engine, a vehicle in particular, to solve the problem of a conventional one-way mechanism having a frictional element, wherein its configuration gets larger when comparing it with a ratchet wheel, etc., for instance. SOLUTION: A one-way mechanism 13 and a planetary roller mechanism 14 are provided in a traction case 16. Therefore, the one-way mechanism 13 and the planetary roller mechanism 14 can be impregnated with common traction oil. At this time, the frictional elements of the one-way mechanism 13 can be brought into contact with each other through the traction oil. Torque transmittable by frictional contact is proportional to shear force of the traction oil. Since the traction oil is solidified under a high pressure, the same contact pressure can still lock larger torque than that of a conventional one-way mechanism, and the one-way mechanism can be made smaller than a normal one. |
