Further, this causes a problem of a large meshing sound between the chain and the sprocket. Conventionally, as a countermeasure for reducing the meshing sound, a vibration isolation member is attached to the engine to absorb the radiated sound, or a vibration isolation rubber is bonded to reduce the noise and vibration by utilizing the characteristics of the rubber. However, if the load of the transmission device transmitting the rotation of the crankshaft to the camshaft increases, the tension of the chain increases, and the meshing sound increases, so that the current noise level cannot be suppressed only by the vibration-proof material, and in the prior art, the chain tensioner in the conventional technology has a single function and only plays a tensioning role; the timing chain needs to be lubricated by an oil sprayer arranged on the cylinder body, and an oil way needs to be arranged on the cylinder body, so that the cost is increased.
