Claims

[Scope of utility model registration request]

In a helical intake port configured with a spiral part formed in the intake valve layer and an inlet passage part connected to the spiral part and extending almost straight, the spiral part is branched from the inlet passage part and the spiral part is connected to the spiral part and extends almost straight. A branch passage that communicates with a spiral terminal end of the intake valve is provided adjacent to the inlet passage, and the branch passage is separated from the inlet passage by a partition wall that projects downward from the upper wall surface of the intake port and extends from the inlet passage to around the intake valve stem. , the entire lower space of the branch passage communicates with the inlet passage part in the cross section, and the passage wall of the inlet passage part and the branch passage are integrally connected, and a rotary valve body is provided in the branch passage. A helical intake port is provided in which a valve body is provided to control the intake air flow flowing in the branch passage, and a valve holder that supports the valve body is screwed into a screw hole screwed into the cylinder head via a spacer. .
