PROBLEM TO BE SOLVED: To prevent a core from coming off while securing rubber permeability into a core part.SOLUTION: The steel cord for an elastic crawler has a core formed from a core strand. The core strand is formed from: a core part formed by twisting three core element wires; a first sheath part formed by twisting six first sheath element wires disposed around the periphery of the core part; and a second sheath part formed by twisting twelve second sheath element wires disposed around the periphery of the first sheath part. The core part has a diameter Dc that is 110 to 125% of the diameter D1 of the first sheath element wire. The core element wire includes a patterned element wire that is patterned in a wave shape in a state before it is twisted. The core wire has a twisting direction and a twisting pitch which are equivalent to the twisting direction and the twisting pitch of the first sheath element wire. |
