A connecting link type rubber crawler mounted to the traveling unit of a mobile construction machine, wherein fall-out of the crawler and sinking of turning wheels hardly occur. In the endless rubber crawler, in which core metals (1) are embedded at a predetermined interval, right and left wing portions (1a) and (1a) of the core metal (1) are embedded in a rubber material of a crawler body (2) and connecting portions (m) and (m) of the core metal (1) are exposed at least on the inner peripheral side of the crawler body (2), or are covered by a thin rubber layer, while, connecting portions (m') and (m') are provided at positions of the lower surface between pin holes (6) and (6) in a track link (5), an interval between the two pin holes (6) and (6) is made equal to the center-to-center interval between the adjoining core metals (1) and (1), and the track link (5) is secured to the core metals (1) from the inner peripheral side of the crawler in such a manner that the respective connecting portions (m, m) and (m', m') are superposed so as to coincide with each other vertically. On the other hand, the track links (5) and (5) disposed at a forward position and a rearward position are connected to each other by inserting pins (9) into the pin holes (6) and (6), and a pair of continuous tracks are formed by the track links at both sides of the central portion of the crawler body (2).
