PROBLEM TO BE SOLVED: To make it possible to stably support an energization body for energizing a tension wheel in a tension direction of a crawler belt and to adequately exhibit energization force thereof.SOLUTION: An adjustment mechanism 36 includes: a tension bolt 43 which is fixed to a first support body 33 and extends in a direction of movement of the first support body 33; an engagement body 44 which is engaged with the tension bolt 43; a rotary body 45 which is relatively movable in a direction of movement between itself and the engagement body 44 in the state that the rotary body is so fitted into the engagement body 44 as to be rotated integrally with the engagement body 44; an operation part 46 for rotationally operating the rotary body 45; and a second support body 26 which is fixed to a truck frame 16 and rotatably supports the rotary body 45, and through which the operation part 46 is penetrated and disposed. An energization body 35 is received and supported by a first support wall part 49 provided on the engagement body 44 at one end part thereof, and is further received and supported by a second support wall part 40 provided on the second support body 26 at the other end part thereof.
【課題】クローラベルトの緊張方向にテンション輪を付勢するための付勢体を安定支持することができ、その付勢力を適切に発揮すること。【解決手段】調整機構36は、第1支持体33に固定されて第1支持体33の移動方向に延びるテンションボルト43と、そのテンションボルト43に螺合された螺合体44と、その螺合体44と一体回転するように螺合体44に嵌合された状態でその螺合体44との間で移動方向に相対移動自在な回転体45と、その回転体45を回転操作するための操作部46と、トラックフレーム16に固定されて回転体45を回転自在のみに支持して操作部46を貫通配置する第2支持体26とを備え、付勢体35は、その一端部が螺合体44に備えられた第1支持壁部49により受け止め支持され、その他端部が第2支持体26に備えられた第2支持壁部40により受け止め支持されている。【選択図】図3
