Beschreibung
Zusammenfassung:	An anti-freezing apparatus for a device for reducing blow-by gas is provided to prevent heat loss due to direct contact between blow-by gas and cold wind when the blow-by gas moves through an intake manifold. An anti-freezing apparatus for a device for reducing blow-by gas comprises an intake manifold(13). A nipple(14) connected with a PCV(Positive Crankcase Ventilation) hose(12) is formed in the intake manifold. A blow-by gas passage communicating with the nipple is formed in the direction in which the blow-by gas passage crosses the outer surface of each runner(13a) of the intake manifold. A vacuum chamber(13c) is formed in the outer surface of the intake manifold such that the vacuum chamber surrounds the blow-by gas passage. A cover is installed at the upper portion of the vacuum chamber to cover the blow-by gas passage. The blow-by gas passage is connected with each runner through a communication hole.
