To provide a track plate having a high mud guarding performance without impairing travelling stability of a crawler type vehicle and to provide a technique relating to this.SOLUTION: A shoe plate 8 has such a rectangular shape that a width direction WD orthogonal to a movement direction TD of a crawler shoe 6 is longer than the movement direction TD. Protrusion parts 81, 82, 83 which are protruded to the side of a ground surface and are elongated horizontally and in a straight line shape in the width direction WD are provided at intervals in the movement direction TD on the grounding surface of the side that grounds to the ground surface of the shoe plate 8. A recessed part 84 including a bottom surface 841 (841A, 841B, 841C) is provided between the protrusion part 81 and the protrusion part 82, and a recessed part 85 including a bottom surface 851 (851A, 851B, 851C) is formed between the protrusion part 82 and the protrusion part 83. The bottom surfaces 841A, 841B, 851A, 851B are inclined so that the depth of the recessed parts 84, 85 becomes deeper as it proceeds to the lateral side from the center side with regard to the width direction WD.SELECTED DRAWING: Figure 5
【課題】クローラ式車両の走行安定性を損なうことなく高い泥除け性能を備えた履板及びこれに関連する技術の提供。【解決手段】シュープレート8は、クローラシュー6の移動方向TDに直交する幅方向WDが移動方向TDよりも長尺な矩形状を有する。シュープレート8のうち地面に接地する側の接地面には、当該地面の側に突出して幅方向WDに水平かつ直線状に延在する突出部81,82,83が移動方向TDに間隔を空けて設けられている。突出部81と突出部82との間には底面841(841A,841B,841C)を含む凹部84が形成され、突出部82と突出部83との間には底面851(851A,851B,851C)を含む凹部85が形成されている。底面841A,841B,851A,851Bは、幅方向WDに関して中心側から側方側に向かうにつれて凹部84,85の深さが深くなるように傾斜している。【選択図】図5
