VALVES INCORPORATED STRUCTURE IN A TENSION ADJUSTING CYLINDER BODY FOR A CRAWLER TYPE VEHICLE

摘要

Valves 4,5 are disposed in such a portion which is defined in an end portion of a piston 30 of an adjusting cylinder body 1 and which does not contact a load giving body 7, thereby preventing deformation by compression caused in incorporation positions of the valves 4,5 and leakage of a filling within the cylinder body 1.
