機伝動機構。 In an engine that drives a valve train, a balancer, and other auxiliary equipment through a flexible endless member when the crankshaft rotates, a rotating body such as a pulley or a sprocket is integrally provided at one end of the crankshaft, In an auxiliary power transmission mechanism in which a rotating body for driving the valve mechanism is disposed above the crankshaft rotating body, one side is connected to a line connecting the crankshaft and the valve mechanism driving rotating body. A balancer is disposed closer to the crankshaft than the auxiliary machine and closer to the tensioner, and a rotating body for driving the auxiliary machine, the crankshaft rotating body, and the moving body are disposed closer to the crankshaft than the auxiliary machine. The inner surface of the flexible endless member is brought into contact with a rotating body for driving a valve mechanism, and
The flexible endless member is arranged such that the outer surface of the flexible endless member is in contact with a rotating body for driving the balancer, and the rotating body for driving the balancer is located on the tension side of the flexible endless member. The member is suspended between the crankshaft rotating body, the balancer driving rotating body, the auxiliary equipment driving rotating body, the valve mechanism driving rotating body, and the tensioner, and a torsional damper is attached to the crankshaft or the crankshaft rotating body. An auxiliary transmission mechanism for an engine characterized by:
