The objective of the present invention is to suppress the concentration of deformation that occurs around embedded members embedded in rubber projections. A rubber crawler (10) has the following: a rubber belt (12) that is wound around a drive wheel; a plurality of hill-shaped rubber projections (14), gradually widening from the peak to the base when viewed from width direction of the crawler, disposed on the rubber belt (12) in the circumferential direction of the crawler with space therebetween and projecting towards the inner circumference of the crawler, to which drive power is input through the engagement of the circumferential direction rubber wall surface (14A) of the rubber projection with an engaging pin (101) of the drive wheel; and an embedded member (30) that is embedded in the rubber projection (14) and in which the circumferential direction wall surface (30A) follows the circumferential direction of the rubber wall surface (14A) when viewed from a cross section that follows the circumferential direction of the crawler.
