WIPO Patent Application WO/2012/070609

A1

Provided is a rubber track (10) comprising a track body (11) formed in an endless belt-like shape using a rubber material. Lug sections (14, 15) are provided on the outer peripheral surface (11b) of the track body (11) at intervals in the circumferential direction (A) of the track so as to protrude from the outer peripheral surface. In the track body (11), engagement sections (17) engaging with the wheels of the track type vehicle are arranged at portions (16) located between lug sections (14, 15) adjacent to each other in the circumferential direction (A) of the track. Through-groove sections (24, 25) penetrating through the lug sections (14, 15) in the circumferential direction (A) of the track are formed in the lug sections (14, 15). The top surfaces (14a, 15a) of the lug sections (14, 15) form ground contact surfaces (26), and the area of the portion of each of the ground contact surfaces (26) which is located on each of both sides of an imaginary line (L) in the width direction (B) of the track is different, the imaginary line (L) extending in the circumferential direction (A) of the track along the entire circumference thereof and passing through the engagement sections (17).
