The invention provides a caterpillar track device and a caterpillar track provided with the caterpillar track device, wherein a caterpillar track can be formed at low cost and a lubricant can be properly sealed. The chain rail device (12) is provided with an embedding part (45) for embedding the sealing component (43) at at least one of the end part of the bush (21) and the periphery of the second hole part (36) of the chain rail (20) which is opposite to the end part of the bush (21) with a gap (46) being arranged between the end part of the bush (21) and the periphery of the second hole part (36) of the chain rail (20). As a result of axial deformation of the seal member (43) fitted in the fitting section (45), the end of the bush (21) can be supported by a support member that is harder than the seal member (43).
本发明提供一种能够以低成本形成链轨、并能够适当地密封润滑剂的链轨装置及具备该链轨装置的履带。链轨装置(12)在衬套(21)的端部和隔着间隙(46)与衬套(21)的端部相对的链轨(20)的第二孔部(36)的周边中的至少一处形成有供密封部件(43)嵌装的嵌装部(45)。由于嵌装于嵌装部(45)的密封部件(43)的轴向变形,衬套(21)的端部可以由比密封部件(43)更硬的支撑部件来支撑。
