Zusammenfassung:	Crawler travelling devices each including a tension wheel of which only a roller part can be replaced are in demand. A tension wheel (15) of the present invention is provided with: a boss part (81) which is rotatably supported by a support shaft (84) supported by a tension frame (19); a roller part (82) which is attached to the outer peripheral section of the boss part (81) and which acts on a crawler belt (18); and a connecting part (C) which disconnectably connects the boss part (81) to the roller part (82). 希望实现种能够仅更换张紧轮的辊部的履带行驶装置。张紧轮(15)具有：轮毂部(81)，以能够旋转的方式支承在支轴(84)，支轴(84)支承在张紧框架(19)；辊部(82)，安装在轮毂部(81)的外周部，并且作用于履带(18)；以及连结部(C)，以能够解除连结的方式连结轮毂部(81)和辊部(82)。
