Description: BACKGROUND OF THE INVENTION Field of the Invention This invention relates generally to a window regulator apparatus, and more particularly to a window regulator apparatus of a wire type. Generally, a window regulator apparatus of a wire type as a prior art is known, for example, by Japanese Utility Model Laid-Open No. 62(1987) - 671. This window regulator comprises a door, a window glass up- and downwardly movably supported on the door, a guide rail fixed in the door and rotatably supporting pulleys at upper and lower portions thereof, a driving mechanism laterally fixed between the pulleys in the door, a wire hung between the pulleys and the driving mechanism, a bracket fixedly connected to the window glass and connected to the wire, and a roller fixed to the bracket and slidably provided on the guide rail, thereby moving the wire by actuating the driving mechanism and up- and downwardly moving the window glass through the roller and bracket. A further window regulator apparatus of said wire type is known from DE-A-2 836 032. However, rattling of the window glass in the longitudinal and width directions of the door is restricted by reducing a clearance between the roller and guide rail as much as possible in the above mentioned prior art. Therefore, it is very difficult to control the above clearance, and if the clearance is reduced, rattling of the window glass can be limited, however, the roller is interfered with the guide rail, thereby generating noise and poor condition upon operation such like heavy operation. In case that the clearance is enlarged, the poor condition upon operation generated by interference between the roller and window glass can be improved, however, rattling of the window glass is increased. SUMMARY OF THE INVENTION One of the objects of the present invention is to provide an improved window regulator apparatus that overcomes the foregoing disadvantages of the prior art. Another object of the present invention is to provide an improved window regulator apparatus, wherein shoe means is interposed between a guide rail and bracket via resilient means, whereby it is prevented from the generation of poor condition upon operation and rattling of a window glass is eliminated. To accomplish these and other objects, the window regulator apparatus according to the present invention is provided with shoe means interposed between a guide rail and bracket for absorbing rattling of longitudinal and width directions of a door via resilient means. BRIEF DESCRIPTION OF THE DRAWINGS Various other objects, features and advantages of the present invention will be more fully appreciated as the present invention becomes better understood from the following detailed description when considered in connection with accompanying drawings, wherein Fig. 1 shows a plain view of a window regulator apparatus according to the present invention; Fig. 2,3 are sectional views showing a main portion of Fig. 1; and Fig. 4 is a view similar to Fig. 1, however, showing a shoe. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to Fig. 1, a window glass 2 is up- and downwardly movably disposed in a door 1. A guide rail 3 is fixedly connected in the door 1 thereto. Pulleys 4,4 are rotatably mounted on upper and lower portions of the guide rail 3. A driving mechanism 5 is laterally located between pulleys 4,4 and is fixed to the door 1. A wire 6 is hung on pulleys 4,4 and driving mechanism 5 in a triangular shape. A bracket 7 is fixed to a lower portion of the window glass 2 and is fixed to the wire 6 through a hook 8. When the driving mechanism 5 is actuated in the window regulator apparatus according to the above mentioned construction, the wire 6 and the window glass 2 is up- and downwardly moved along the guide rail 3 through bracket 7 and hook 8. As shown in Figs. 1 to 3, shoes 10,11 are interposed between the guide rail 3 and bracket 7 through resilient means 9. The shoes 10,11 are provided so as to always depress the resilient means 9. Rattling of the bracket 7 into the longitudinal direction of the door 1 (direction A shown in Fig. 2) to the guide rail 3 is absorbed by deflection of the resilient means 9 via the shoe 10, and rattling of the bracket 7 into the width direction of the door 1 (direction B shown in Fig. 3) to the guide rail 3 is absorbed by deflection of the resilient means 9 via the shoe 11. As above mentioned, rattling of the bracket 7 to the guide rail 3 is absorbed by the resilient means 9, so that rattlings of the window glass 2 into the longitudinal and width directions of the door 1 can be reduced and the bracket 7 and guide rail 3 are not interfered by shoes 10,11. Accordingly, the generation of noise and poor condition upon operation such like heavy operation can be removed. Further, resilient means 9 and shoes 10,11 are located in a pair into up- and downward directions, so that the rotation around the center of shoes 10,11 can be prevented and the stability of the window glass 2 can be improved. According to the present invention, the window regulator apparatus includes the door 1, the window glass 2 up- and downwardly movably supported on the door 1, the guide rail 3 fixedly connected to the door 1 and rotatably supporting pulleys 4,4 , the driving mechanism 5 laterally fixed to the door 1 between pulleys 4,4 therewithin, the wire 6 hung on pulleys 4,4 and driving mechanism 5, and the bracket 7 fixed to the window glass 2 and connected to the wire 6. The shoes 10,11 are interposed between the guide rail 3 and bracket 7 through the resilient means 9. Consequently, rattlings of the window glass 2 into the longitudinal and width directions of the door 1 can be reduced and the bracket 7 and guide rail 3 are not interfered by shoes 10,11. As this result, the generation of noise and poor condition upon operation such like heavy operation can be removed. The principles, preferred embodiments and mode of operation of the present invention have been described in the foregoing application. The invention which is intended to be protected herein should not, however, be construed as limited to the particular forms disclosed, as these are to be regarded as illustrative rather than restrictive. A window regulator apparatus includes a guide rail fixed within a door, pulleys rotatably supported on the guide rail at upper and lower portions thereof, a driving mechanism fixed within the door for up- and downwardly moving a window glass along the guide rail, a wire hung on the pulleys and driving mechanism for transmitting a moving force to the window glass, a bracket fixedly connected to the wire, resilient means interposed between the rail member and bracket member, and shoe means interposed between the resilient means and guide rail.
