PROBLEM TO BE SOLVED: To provide highly reliable upper and lower rolling wheels for a crawler type traveling vehicle, capable of dealing with high-speed traveling and facilitating assembling.SOLUTION: Upper and lower rolling wheels constituting parts of a crawler type traveling vehicle are structured in such a manner that bearing means arranged left and right include a pair of conical roller bearings 11 and 12 fitted around a shaft 2, the pressurization means of the conical roller bearings 11 and 12 is installed at the end of the shaft 2, the pressurization means inserts a push bolt 61 into the shaft 2, and fastens a pressing member 5 and the shaft 2 together with a positive space to apply a pressurization force. As the looseness prevention means of the push bolt 61, a push bolt 62 is inserted into the pressing member 5.SELECTED DRAWING: Figure 1
【課題】高速走行に対応することができ、しかも組立の容易化を図ると共に、信頼性に優れた履帯式走行車両の上・下転輪を提供することである。【解決手段】履帯式走行車両の一部を構成する上・下転輪であって、左右に配置された軸受手段がシャフト2に外嵌される一対の円すいころ軸受11、12により構成され、円すいころ軸受11,12の与圧手段がシャフト2の軸端に設置され、上記与圧手段は押し付けボルト61をシャフト2に挿入し、押し付け部材5とシャフト2とを、正のすきまを設けて締結することにより、与圧力を与える構造であり、かつ、押し付けボルト61の緩み防止手段として、押し付け部材5に、押しボルト62を挿入する。【選択図】図1
