置。[Claims for Utility Model Registration] (1) An intake device for an internal combustion engine equipped with a valve mechanism whose operating state can be varied depending on the operating state, which extends in parallel along a curved intake passage. and an opening/closing control valve that selectively communicates the intake passage with the blind pipe, and the opening/closing control valve is configured to perform the opening/closing control at a rotational speed different from a rotational speed at which the operating state of the valve operating mechanism is switched. An intake device characterized by controlling opening and closing of a valve. (2) An intake device for an internal combustion engine, comprising: blind pipes extending in parallel along a curved intake passage; and an opening/closing control valve that selectively communicates the intake passage with the blind pipe. An intake device comprising: the blind pipe formed by integrally casting with a member defining the intake passage.
