徴とする内燃機関のブローバイガス導入装置。 A throttle body with a built-in throttle valve is joined to an intake manifold for an internal combustion engine in a substantially horizontal direction, and a blow-by gas hole is bored in the throttle body to guide blow-by gas from a cylinder head cover, etc. to the downstream side of the throttle body. In the blow-by gas introduction device, the blow-by gas passage hole in the throttle body includes an outlet hole formed so as to extend in the axial direction of the throttle body from the joining surface of the throttle body to the intake manifold, and an outlet hole that extends from the upper surface of the throttle body to the axis of the throttle body. A blow-by gas for an internal combustion engine, characterized in that the blow-by gas comprises an inlet hole that is downwardly bored at a substantially right angle, and a throttle orifice that communicates the inlet hole with the outlet hole is formed at the bottom of the inlet hole. Introduction device.
