Abstract
An intake device includes: a rotary shaft; and a resin-made intake valve including a rotary shaft press-fit guide hole provided at an end portion in a rotary axis direction to guide the rotary shaft when the rotary shaft is press-fitted, a rotary shaft press-fit hole provided on a more inner side than the rotary shaft press-fit guide hole in the rotary axis direction, the rotary shaft inserted through the rotary shaft press-fit guide hole being press-fitted into the rotary shaft press-fit hole, and a window portion exposing an outer surface of the rotary shaft, the resin intake valve being rotated together with rotation of the rotary shaft in the intake port to change intake air, in which the rotary shaft press-fit guide hole has a tapered shape portion which gradually decreases in cross-sectional area toward the rotary shaft press-fit hole when viewed from the rotary axis direction.
