PURPOSE:To provide compatibility of parts for both cases of presence and absence of oil tappet, by forming a holding section, which can hold a rod in free-to-slide manner, by extending an oil tappet holding body to an air-intake- and-exhaust valve side. CONSTITUTION:By extending a holding body 20 which holds an oil tappet 15, a sliding hole 25 for holding rods 31 and 32 is formed. The holding body 20 is fixed onto a cylinder head 1 in such a manner as to be able to be put on and off with freedom. Since the rods 31 and 32 are used, air-intake-and-exhaust valves 10 and 11 are not required to be made long. This fact makes it possible to use a cylinder head, an air-intake-and-exhaust valve and a valve guide, which are designed for a valve moving device in which an oil tappet is not employed. |
