PROBLEM TO BE SOLVED: To provide a construction machine including a crawler as a device for enabling an operator to surely recognize the traveling direction of a lower traveling body at low production cost.SOLUTION: A construction machine includes an upper rotation body rotatably provided in a lower traveling body, a cockpit disposed in the front part of the upper rotation body, an idler wheel provided on one end side of a side frame, a driving wheel provided on the other end side of the side frame, and a crawler wound and set between the idler wheel and the driving wheel. The crawler 16 includes many track links 20 connected in an endless annular shape by connection pins 22 and bushes 21, and a track plate 23 fitted to each of the track links in a direction vertically orthogonal to the direction for connecting many track links, and the front end and the rear end of the track plate disposed in the longitudinal direction of the crawler are different from each other in shape.SELECTED DRAWING: Figure 3 |
