PROBLEM TO BE SOLVED: To more stably mount a connection plate to a support plate.SOLUTION: An undercarriage 51 of a working machine 1 is provided with a pair of crawler frames 65 detachably mounted to a car body 62 through a support mechanism 10. The support mechanism 10 includes an inner connection part 73 located on the car body 62 side, and an outer connection part 74 located on the crawler frame 65 side. The inner connection part 73 includes a connection plate 82 welded to a support plate 81, welded to the car body 62, in orthogonal to the support plate 81, and a reinforcement plate 11 welded to a lower end part of the inner connection part 73. The outer connection part 74 includes a bracket 74a connected to the connection plate 82 through a connection shaft 78. The reinforcement plate 11 includes a base part 11a extending along the support plate 81, and an extension part 11b orthogonal to the base part 11a and extending along the lower side of the connection plate 82. |
