The invention discloses a protective cover device for reducing wind noise of a front vertical plate of a car of an elevator. The protective cover device comprises the front vertical plate with the car of the elevator. Vent holes are distributed in the front vertical plate. An outer cover plate used for shielding the areas of the vent holes is fixed to the outer side of the car of the front vertical plate. An air inlet is formed in the outer cover plate. Due to the fact that the outer cover plate is fixed to the outer side of the front vertical plate and the vent holes in the front vertical plate are shielded by the outer cover plate, air can enter the vent holes of the front vertical plate in a detoured manner only through the air inlet in the outer cover plate, no strong air flow can be directly generated, wind noise caused by the vent holes of the front vertical plate is reduced, and the effect is remarkable.
