The present invention relates to a belt support for a chain belt-type variable transmission for controlling a transmission gear ratio, in which a chain belt is wound to a driving pulley device and to a driven pulley device having variable diameters, and more particularly, in which the tooth profile of front and rear latch gear portions formed in opposite direction while the latch gear portions are divided into front and rear portions and are formed on a plurality of driving side belt supports and driven side belt supports, each of which is radially and expandably installed on the driving pulley device and the driven pulley device so as to have a predetermined distance therebetween, wherein each of the latch gear portions that are formed on the driving belt support and each of the tooth profiles of the latch gear portions that are formed on the driven side belt support face opposite sides, so that each of the latch gear portions that are formed on the driving side belt support and on the driven side belt support are installed so as to crisscross and not be on one line, and wherein a main body of the belt support is formed obliquely in a helical gear shape, and a front body, which is provided with the front latch gear portion, and a rear body, which is provided with the rear latch gear portion, are coupled and installed thereon so as to be attachable/detachable. |
