To provide a core member for a crawler and an elastic crawler which can reduce the weight by reduction with resin and provide required mechanical characteristics in a well-balanced manner.SOLUTION: A core member 10 for a crawler is made of resin. The core member 10 includes a pair of protrusions 11, 11, a pair of blade portions 12, 12, and ribs 13, 13. The ribs 13 each extend in a longitudinal direction. The rib 13 is connected to the protrusion 11. Further, the rib 13 includes a rib thickness gradually decreasing portion 132 where a thickness d in a short direction of the rib 13 gradually decreases toward the outer side in the longitudinal direction. An elastic crawler 100 includes the core member 10 and an endless strip-shaped elastic member 20.SELECTED DRAWING: Figure 7
