Claims

[Scope of utility model registration request]

A tilt type cab is supported by the chassis frame via an elastic member, and one end is connected to the chassis frame and the other end is connected to the cab via a link to allow vertical displacement of the cab in the traveling position. A mower comprising a power cylinder for cab tilt connected to the mower, and configured such that tilting of the cab is started after the link comes into contact with a fixing member on the cab side due to extension of the power cylinder, A locking member provided at the other end of the power cylinder and a portion of the cab near the link include a first position that does not inhibit displacement of the locking member due to vertical displacement of the cab in the traveling position; a hook lever supported so as to be rotatable to a second position that engages with a locking member and prevents the cab from falling forward; and a hook lever that is biased by an elastic member to maintain the unlatched position. The hook lever is held at the first position by the biasing force of the elastic member when the cab is in the traveling position, and the power cylinder is extended to set a distance between the link and the fixed member. The front of the tilt-type cab is characterized in that when the value becomes smaller than the above-mentioned value, the front of the tilt-type cab is configured such that the front of the tilt-type cab comes into contact with the link and is held at the second position against the biasing force of the elastic member along with the displacement of the link. Fall prevention device.
