BASE CARRIER OF CONSTRUCTION MACHINE
To allow easy replacement of shims adapted to adjust a clearance between an axle and a guide port of a crawler frame.SOLUTION: A first shim 30 and a second shim 40 are housed in an overlapped manner at a step part 16 on an upper surface of an axle 15. A tightening bolt 25 is tightened into a screw hole 17 formed in a side wall surface of the step part 16. As the tightening bolt 25 is being tightened, the first shim 30 is pushed by a head portion 27 of the tightening bolt 25 to move in a tightening direction. The second shim 40 is sandwiched between the first shim 30 and an inner side wall of the step part 16 in the vehicle width direction to move obliquely upward along a first inclined portion 31 of the first shim 30.SELECTED DRAWING: Figure 13
【課題】アクスルとクローラフレームのガイド口との隙間を調整するシムを交換し易くする。【解決手段】アクスル１５の上面の段差部１６には、第１シム３０と第２シム４０とが重ね合わされて収容されている。段差部１６の側壁面に形成されたネジ孔１７には、締結ボルト２５が締結されている。締結ボルト２５を締め付けていくと、締結ボルト２５の頭部２７によって第１シム３０が押し込まれ、締め付け方向に移動する。第２シム４０は、第１シム３０と段差部１６の車幅方向の内側の側壁との間に挟まれて、第１シム３０の第１傾斜部３１に沿って斜め上方に移動する。【選択図】図１３
