Claims

[Scope of utility model registration request]

A bypass valve that opens and closes a common pass passage of a helical intake port is rotatably supported by a valve body inserted into the bypass passage, coupled to the valve body and supported by the cylinder head via a guide. 1. A flow path control device for a helical-type intake port, characterized in that the valve body and the shaft portion are integrally formed by projection welding.
