An elastic crawler and an elastic crawler drive mechanism collectively suppress the interference between the pin members and the engaging portions, and improve the durability of the engaging portions. The elastic crawler includes on an inner circumferential side thereof a plurality of engaging portions (14) respectively engageable with a plurality of pin members (22) arranged at a spacing in a circumferential direction of a sprocket, wherein: the engaging portions (14) have a pressure receiving surface (14a) which receives the pin members (22), an outline shape in side view of the pressure receiving surface (14a) being formed by an envelope L1 drawn by an outer end of the pin members (22) when the sprocket rolls coaxially with a central axis of a virtual rotor with a rolling diameter D1 defined by D1=(pitch of the engaging portions)×(number of pin members)/(π)×a, and 0.9≤a≤1, together with the virtual rotor on a plane.
