The present invention relates to an undercarriage equipped with a non-steel type rubber crawler using chain action, particularly to an undercarriage of a track system for a skid loader in which an auxiliary sprocket axis and an auxiliary sprocket are equipped to solve load concentration at the contact of a non-steel type rubber crawler, which is adopted to reduce total load of a vehicle, and cogs of a sprocket and a gearchain is equipped surrounding a main sprocket axis and the auxiliary sprocket axis, so that it receives the load dispersed over the large contact area of the non-steel type rubber crawler, thereby relieving internal stress concentration at the sprocket and the non-steel type rubber crawler and significantly improving life cycle of the non-steel type rubber crawler.
