What is claimed is: 1. In combination, a door panel and a wiper structure for a window glass, said combination comprising: said door panel configured to fit on a vehicle and having an opening formed therein; a curved window glass adapted to fit inside the opening, wherein said window glass includes a large curvature portion; a wiper arm; a support arm provided on the wiper arm; and a wiper blade comprising a blade main body, the wiper blade being operatively supported on the wiper arm about a connecting point, the wiper blade main body being supported at a plurality of support points on the support arm, wherein a spacing between any two adjacent support points of the plurality of support points is set wider as a curvature of the window glass increases, wherein a portion where the curvature of the window glass is large is formed across the widthwise direction of the vehicle, the vertical curvature increases across the widthwise direction of the vehicle, and the lower portion is curved sharply downward, and wherein said wiper blade support arm is configured such that during operation, when the wiper blade reaches a position which crosses over the large curvature portion of the window glass at right angles, a bend space is kept in the height direction of the blade main body. 2. A combined door panel and wiper structure according to claim 1, wherein the wiper blade is supported on the wiper arm in an asymmetrical manner about the connecting point, and wherein the wiper blade is set such that a length from the connecting point is shorter on a side having a greater curvature of the window glass. 3. In combination, a door panel and a tournament-type wiper structure for a window glass, said combination comprising: said door panel configured to fit on a vehicle and having an opening formed therein; a curved window glass adapted to fit inside the opening, wherein said window glass includes a large curvature portion; a pivot shaft; a wiper arm connected to the pivot shaft; a support arm provided on the wiper arm; and a wiper blade comprising a blade main body, the wiper blade being operatively supported on the wiper arm about a connecting point, the wiper blade main body being supported at a plurality of support points on the support arm, wherein the number of levels in the tournament is set smaller as a curvature of the window glass increases, and wherein a portion where the curvature of the window glass is large is formed across the widthwise direction of the vehicle, the vertical curvature increases across the widthwise direction of the vehicle, and the lower portion is curved sharply downward, and wherein when the wiper blade reaches the position which crosses over the large curvature portion of the window glass at right angles, a bend space is kept in the height direction of the blade main body. 4. A combined door panel and wiper structure according to claim 3, wherein the wiper blade is supported on the wiper arm in an asymmetrical manner about the connecting point, and wherein the wiper blade is set such that a length from the connecting point is shorter on a side having a greater curvature of the window glass. 5. In combination, a door panel and a tournament-type wiper structure for a window glass, said combination comprising: said door panel configured to fit on a vehicle and having opening formed therein; a curved window glass adapted to fit inside the opening, wherein said window glass includes a large curvature portion; a wiper arm comprising a support arm provided on the wiper arm; and a wiper blade comprising a blade main body, the wiper blade being supported on the wiper arm about a connecting point, the wiper blade main body being supported at a plurality of support points on the support arm, wherein the number of levels in the tournament is set smaller as a curvature of the window glass increases, and a spacing between any two adjacent support points of the plurality of support points is set wider for the large curvature portion of the window glass, and wherein a portion where the curvature of the window glass is large is formed across the widthwise direction of the vehicle, the vertical curvature increases across the widthwise direction of the vehicle, and the lower portion is curved sharply downward, and wherein when the wiper blade reaches the position which crosses over the large curvature portion of the window glass at right angles, a bend space is kept in the height direction of the blade main body. 6. A combined door panel and wiper structure according to claim 5, wherein the wiper blade is supported on the wiper arm in an asymmetrical manner about the connecting point, and wherein the wiper blade is set such that a length from the connecting point is shorter on a side having a greater curvature of the window glass. 7. A rear door panel assembly for a vehicle, said rear door panel assembly comprising: a door panel having an opening formed therein, a curved window glass adapted to fit inside the opening of said door panel, said window glass comprising a large curvature portion; a pivot shaft operatively attached to the door panel; and a wiper apparatus, comprising: a wiper arm connected to the pivot shaft, a wiper blade support structure attached to the wiper arm; and a wiper blade comprising a blade main body, the wiper blade being operatively supported on the wiper arm by the wiper blade support structure, the blade main body being supported at a plurality of support points on the wiper blade support structure, wherein the wiper blade support structure comprises: a primary arm pivotally attached to said wiper arm, said primary arm having a proximal end and a distal end; a first support arm pivotally connected to the proximal end of the primary arm at a pivot connection, said first support arm having an outwardly bowed substantially arcuate shape and having a respective support point for supportingly receiving a portion of the wiper blade therethrough at each end thereof; a second support arm pivotally connected to the distal end of the primary arm, said second support arm having a proximal end and a distal end, said proximal end of the second support arm having a support point thereon for supportingly receiving a portion of the wiper blade therethrough; and a yoke which is pivotally attached to the distal end of said second support arm, said yoke having an outwardly bowed substantially arcuate shape and having a respective support point for supportingly receiving a portion of the wiper blade therethrough at each end thereof; and wherein the large curvature portion of the window glass extends across the window glass in a widthwise direction of the door panel, and the lower portion of the window glass extends sharply downward from the large curvature portion, and wherein said wiper blade support structure is configured such that during operation, when the wiper blade crosses over the large curvature portion of the window glass, a bend space is maintained between an outer surface of the main blade body and an inner surface of the first support arm at an area thereof proximate the pivot connection between the primary arm and the first support arm. 8. A rear door panel assembly according to claim 7, wherein the wiper blade is set such that a length from the connecting point is shorter on a side having a greater curvature of the window glass, and wherein the wiper blade is supported about the connecting point on the wiper arm in an asymmetrical manner.
