Claims

[Scope of utility model registration request]

A cab support device in which a cab-side bracket fixed to a tiltable cab is brought into contact with an elastic member disposed in a receiving portion of a chassis-side bracket, and the cab is elastically supported on a chassis, wherein the cab-side bracket is placed in the receiving portion. The elastic member is composed of a first elastic member having a small spring constant that is first compressively deformed by the cab side bracket, and a second elastic member having a large spring constant that is compressively deformed after the first elastic member is compressively deformed. A support device for a cab, which is characterized by the following:
