An air deflector (10) is attached to a roof of a cab (2). A rear edge portion (12) of the air deflector has a configuration identical with an upper part of a vertical front face ( 4) of a van body (3) or a configuration closely resembling the upper part thereof, as viewed from the front. A marker lamp (40) is located on a ridge portion (32) of the air deflector in proximity to the rear edge portion. An upper surface (41) and a side surface (43) of the marker lamp are formed to continue an upper face (31) and a side face (33) of the air deflector, and a ridge portion (42) of the marker lamp is in alignment with the ridge portion of the air deflector. The air deflector can ensure visibility of the marker lamps, while preventing the flow of air from impinging on the upper corner areas of the front face of the van body, whereby the aerodynamic performance of the vehicle is improved.

What is claimed is: 1. An air deflector, which is attached to a vehicle provided with a cab and a van body in a form of box and which is mounted on a roof of the cab so as to improve an aerodynamic performance of the vehicle, comprising; a marker lamp located in proximity to a rear edge portion of the air deflector opposed against a vertical front face of the van body, wherein the marker lamp is positioned on a ridge portion connecting a side face of the air deflector and a frontward inclined upper face thereof. 2. An air deflector as defined in claim 1, wherein an upper surface of said marker lamp is formed to be substantially flush with said upper face of the air deflector, so that a continuous upper surface of the air deflector is formed; a side surface of the marker lamp is formed to be substantially flush with said side face of the air deflector, so that a continuous side surface of the air deflector is formed; and a ridge portion joining the upper and side surfaces of the marker lamp is in alignment with the ridge portion of the air deflector so as to form a continuous ridge of the air deflector. 3. An air deflector as defined in claim 1, wherein said rear edge portion of the air deflector has a configuration identical with said front face of the van body or a configuration closely resembling the front face, as viewed from the front of the vehicle. 4. An air deflector as defined in claim 1, wherein a surface of the air deflector is configured to direct the flow of air outward of top and side edges of said vertical front face of the van body. 5. An air deflector as defined in claim 3, wherein a width (W3) and a height (H2) of said rear edge portion of the air deflector is set to be substantially equal to a width (W1) and a height (H1) of an upper part of said front face, respectively. 6. An air deflector as defined in claim 4, wherein at least one of a width (W3) and a height (H2) of the rear edge portion is set to be less than a width (W1) or a height (H1) of an upper part of said front face, wherein an extension line (E) of the rear edge intersects the edge of the vertical front face of the van body, or extends outward thereof. 7. An air deflector as defined in claim 2, wherein said upper and side surfaces of the marker lamp are configured to enlarge rearward along said ridge portion of the air deflector. 8. An air deflector as defined in claim 1, wherein the air deflector has a base part mounted on the roof of the cab, an upper panel attached onto the base part, and angle adjusting means for adjusting an angle of the upper panel with respect to the base part. 9. An air deflector as defined in claim 8, wherein said angle adjusting means includes a pivot joint which pivotally supports said upper panel for rotation about a horizontal axis, and a locking mechanism which engages with the upper panel so as to secure the panel in a desired level. 10. An air deflector as defined in claim 8, wherein the base part has a supporting section for supporting the upper panel, and a boundary between the supporting section and the front and side faces of said base part is formed by a stepped edge; and wherein, inside of the boundary, the supporting section is recessed by the stepped edge, and the upper panel is attached to the supporting section so that a surface of the upper panel is substantially flush with a surface of the base part. 11. An air deflector as defined in claim 8, wherein said upper panel has a ridge portion and a marker lamp mount section on the ridge portion, and wherein the marker lamp is positioned in a cavity or recess of the marker lamp mount section; and wherein a lens of the marker lamp has an outer edge profile matching with a frame of the mount section, and an outer peripheral edge of the lens is fixed to the frame. 12. An air deflector as defined in claim 1, wherein the upper part of said front face of the van body is substantially fully covered with the air deflector, as viewed from the front, whereby a stepped formation is substantially completely eliminated between the air deflector and the van body.
