PROBLEM TO BE SOLVED: To fix a restriction mechanism which blocks abnormal tilting of a cab, without providing a welding portion.SOLUTION: A restriction mechanism 40 comprises an engage shaft 41, an engage plate 48, and a fastening member 50. The engage shaft 41 is mounted to a left rear part of a cab 30 and extends toward a bottom plate 21 of an upper frame 20 while protruding downward. The engage plate 48 is disposed to face the bottom plate 21 with a clearance interposed therebetween while forming an engage hole 48a having a larger inner diameter than an outer diameter of the engage shaft 41 beforehand. The fastening member 50 fastens and fixes the engage plate 48 to the bottom plate 21 in the state where the engage shaft 41 is inserted into the engage hole 48a and the center of the engage hole 48a is matched with an axial center of the engage shaft 41. |
