PROBLEM TO BE SOLVED: To install support shafts in an engine body by reducing the number of part items and installing manhours without increasing a cost in a valve system of an engine for inserting and supporting the support shafts having both ends opposed to a wall equipped in the engine body into and by a plurality of shaft support parts arranged in the engine body, and rockably supporting an arm by the support shafts. SOLUTION: The support shafts 88 and 89 are formed so that a plurality of divided shaft parts 88a to 88c and 89a to 89c divided shorter than the length between at least one 90A and 91G and the wall 29a of a pair of shaft support parts 90A, 90G and 91A, 91G opposed to the wall 29a among the plurality of shaft support parts 90A to 90G, and 91A to 91G, are inserted into and supported by at least one of the shaft support parts 90A to 90G, and 91A to 91G, respectively and are allowed to abut on each other in the shaft direction.
