Intake apparatus and manufacturing method for the same

An intake apparatus includes housings each defining an intake passage therein. The intake apparatus further includes valve members each being provided to each housing for communicating and blocking the intake passage. A shaft extends through the housings. The shaft is rotatable integrally with the valve members. A bearing member extends together with the shaft through the housings. The shaft is rotatable in the bearing member. The bearing member includes exposed portions each being exposed to the intake passage. Each exposed portion has an opening that extends with respect to an axial direction of the bearing member. The opening corresponds to a rotatable range, in which the valve member is rotatable with respect to a circumferential direction of the bearing member.
