Abstract

PURPOSE:To obtain a caterpillar capable of riding over the steps of a stair and the like without slipping by restricting the pivotting of an element around the protruded part caught on the step edge as the supporting point. CONSTITUTION:A caterpillar has guide rollers 5 and 5' which engaged with guide grooves G and G', the engaging of said rollers restricting the travelling attitude of a caterpillar element 7 thus preventing the pivotting of the element 7 with a protruded part 9a as its support point when the protruded part 9a of the element 7 catches the step edge S and ride over it, i.e., the pivotting moment of the element 7 when a load is applied to it is restricted by the outside contact point P1 between the roller 5 and the guide groove G and the inside contact point P2 between the adjacent roller 5 and the guide groove G thereby maintaining the attitude of the element and preventing the possibility of slip off of the protruded part 9a caught on the step edge S.
