Claims

[Scope of utility model registration request]

A shutter valve that is disposed in an intake passage communicating with each cylinder of a multi-cylinder engine and has a shaft and a valve body that rotates around the shaft to open and close each intake passage, wherein the shaft is other than the valve body. The divided shaft is divided into at least two parts in the axial direction, and each divided shaft is rotatably biased so that the valve body is fully opened. In this case, a gap is formed so that the rotation of one divided shaft lags behind the rotation of the other divided shafts, and when the shutter valve is closed, the opening degree of the valve body on one divided shaft is equal to that of the remaining divided shafts. An intake shutter valve for an engine, characterized in that the opening is smaller than the opening of a valve body on a shaft.
