  "textContent": "An OHC engine includes a valve operation system housed in a valve operation chamber (116) formed between a cylinder head (50) and a head cover (115) joined to the cylinder head. The valve operation system includes a valve-operating cam (126) and is cooperatively connected to an intake valve (110) and an exhaust valve (111). The OHC engine also includes timing transmitting device (127) disposed between the valve operation system and a crankshaft (44), the timing transmitting means including a driven wheel (131) that rotates together with the valve-operating cam and a transmission belt (132) that is wrapped around the driven wheel so that oil (42) within a crankcase (45) can accompany the transmission belt and be supplied to the valve operation chamber (116). The head cover is provided with an arc-form curved cover part (115b) for covering the upper part of the driven wheel. The curved cover part integrally includes above the driven wheel a plurality of oil splashing ribs (136, 137) that are positioned at intervals along the rotational direction (138) of the driven wheel to project toward the side that is closer to the transmission belt, thereby allowing oil to be supplied uniformly to each section of the valve operation system.",
