Abstract

PURPOSE: To reduce the expansion stroke of piston rod of a grease cylinder and shorten adjustment time, by adjusting the tension of a crawler while a link is provided between the piston rod and a rod secured behind a bearing.
CONSTITUTION: A bearing 3 for supporting a guide wheel 2 is provided at the end of a side frame so that the bearing can be moved along a guide part 1a. A shim 18 is fitted on a rod 17 and interposed between the bearing 3 and a protruded part 1b. The rod 17 slidably extends through the protruded parts 1b, 1c of the side frame. A grease cylinder 28 for displacing the bearing 3 is installed on a pocket 27 provided in the side frame, so that a piston rod 28a is opposed to the rod 17. A link 36 is provided between the rods 28a, 17 and slidably and rotatably mounted on a shaft 37.
