PROBLEM TO BE SOLVED: To provide a sprocket of which abrasion is suppressed, and an elastic crawler drive mechanism using the sprocket.SOLUTION: A sprocket 10 can be engaged to a plurality of core grids 22 disposed in an endless belt body 21 having elasticity. A part of a dedendum of at least any of tooth surfaces F, with a center line Oof a tooth 12 as a boundary, of a tooth 12 of the sprocket 10 is defined as a dedendum surface 21b, and the dedendum surface 21b is inclined at an angle A within a range of 0-7.5° to the center line Oof the tooth 12 so as to get closer to the center line Oof the tooth 12 toward an addendum surface 12d.SELECTED DRAWING: Figure 2

    【課題】スプロケットの摩耗が抑制された、スプロケットおよび当該スプロケットを用いた弾性クローラ駆動機構を提供する。【解決手段】本発明は、弾性を有する無端帯状体21に配設された複数の芯金22と係合可能なスプロケット10である。スプロケット10の歯12の歯面Fの、当該歯12の中心線O2を境にした少なくともいずれか一方の歯元の一部を歯元面21bとし、歯元面21bは、歯先面12dに向かうに従って歯12の中心線O2に接近するように、歯12の中心線O2に対して0°以上7.5°以下の範囲の角度Aで傾斜するものである。【選択図】図2
