To improve strength of an axle insertion part against force acting in a direction such that the force expands an opening of the axle insertion part.SOLUTION: A crawler frame 33 of a crawler type carrier 1 includes an axle insertion part 50 and a frame part 60. The axle insertion part 50 is a portion where an axle (20) is inserted and includes an insertion part protruding part 57. The insertion part protruding part 57 protrudes from a crawler frame body part 40 toward a car body (11) and has an insertion part upper plate 51, an insertion part lower plate 52, an insertion part inner plate 53, and an insertion part outer plate 54. The frame part 60 is fixed to an outer periphery portion of the insertion part protruding part 57 and disposed so as to enclose the insertion part upper plate 51, the insertion part outer plate 54, and the insertion part lower plate 52 continuously.SELECTED DRAWING: Figure 4
