The present invention relates to a cooling fan shroud apparatus for a vehicle with an improved assembly structure of an air flap door, and more specifically, to a shroud device at which a cooling fan constituting a cooling fan apparatus for a vehicle and a motor provided to operate the cooling fan are installed, and which comprises: a shroud body of a plate shape; a door installation hole formed at the shroud body; and an air flap door of a plate shape which is installed to open and close the door installation hole. The present invention further comprises: a hinge shaft of a rod shape, which is horizontally arranged in the upper direction of the door installation hole to be fixed to the shroud body; a pair of hinge coupling units of a cantilever shape, which protrude to the upper side of the air flap door, and which are arranged in a state of being spaced apart at a predetermined interval in a left-and-right direction; a hinge accommodating groove which is formed at the hinge coupling units, and has a specific direction opened, and of which a distal end surface is formed in a shape of a part of an arc; and a guide groove unit which is arranged at the upper portion of the door installation hole, and is formed in a groove portion shape which is concavely cut-out at the shroud body so as not to be interrupted with the hinge coupling units. The hinge coupling units are characterized by being assembled with the hinge shaft in a direction identical to the flowing direction of the air which is applied in the direction in which the air flap door is opened. Therefore, assemblability may be improved.
