<P>PROBLEM TO BE SOLVED: To provide an elastic crawler restricted in the generation of heat between adjacent core metals in travelling and improved in flexibility. <P>SOLUTION: The elastic crawler 10 includes: an elastic crawler body 12 made of a rubber and formed into an endless belt; a plurality of core metals 14 which include a central part 16, a pair of wing parts 18 extending outside in the cross direction of the crawler from the central part 16, and a pair of projections 20 projecting toward an inner peripheral side of the crawler from a boundary part between the central part 16 and the wing parts 18, and which are embedded in the elastic crawler body 12 with an interval in the circumferential direction of the crawler; and a first recess 30 formed in an inner peripheral part of the elastic crawler body 12, extending outside in the cross direction of the crawler from a space between the wing parts 18 adjacent to each other in the circumferential direction of the crawler and recessed toward an outer peripheral side of the crawler in a cross section along the circumferential direction of the crawler. <P>COPYRIGHT: (C)2012,JPO&INPIT |
