PURPOSE: To freely move a front window up and down along roller guide rails by manual operation and to easily remove the same by removably connecting a front window side bracket hardware and a cable side bracket hardware to each other. ;CONSTITUTION: In the case of replacing a front window due to a breakage accident, a bolt 30 is loosened and removed. Whereupon, the connection between a front window side bracket hardware 27 and a cable side bracket hardware 28 is released. Accordingly, a front window 17 is freely move up and down along roller guide rails 21 by manual operation to prepare for removal. A bolt hole bored in the calbleside bracket hadware 28 is formed as an elongaed hole 29 parallel to the axial direction of a cable 22. Thus, if right and left cables are different in the degree of tension, the bolt 30 is loosened to shift the connection between the front window side bracket hardware 27 and the cable side bracket hardware 28, and the degree of tension of right and left cables is adjusted to solve right and left twisting of the front window 17, so that the front window 17 can be smoothly opened and closed.;COPYRIGHT: (C)1994,JPO&Japio
