Claims

[Scope of utility model registration request]

In a flow path control device for a helical intake port, in which a bypass valve for opening and closing a bypass passage of a helical intake port is rotatably supported on a guide, and the guide is attached to a cylinder head, an O-ring is fitted around the guide. The guide is fixed to the cylinder head by inserting it into the bypass valve mounting hole of the cylinder head, and then press-fitting a press-fitting guide, which is a separate member from the guide, into the hole and pressing the guide with the press-fitting guide. Features a helical intake port flow path control device.
