Abstract
The object of the present invention is to facilitate an appropriate oil supply to the tensioner without a complex apparatus. A valve chamber 3A is formed in a cylinder head 3 which is connected to a cylinder block 2. An opening 23—for discharging the oil in the valve chamber 3A into a chain case 6 which is placed on the side of the cylinder block 2—is formed on a chain case mounting surface 20. Inside the chain case 6 on the chain case mounting surface 20 of the cylinder block 2 are placed a timing chain 15 and a tensioner 30 for applying tension to the timing chain 15. An oil dropping rib 24 for guiding the oil discharged through the opening 23 to the tensioner 30 is provided on the chain case mounting surface 20.
