PURPOSE: To suppress deformation of a cab and a rear arch by producing the dispersion of a load through effective utilization of a floor frame being the main skeleton of the carburetor. CONSTITUTION: In a truck wherein the central part of the rear end of a cab 2 mounted on a car body frame 1 inclinably centering around the lower part of a front end is disengageably engaged with the central part of a rear arch 3 fixed to the car body frame 1 through a lock mechanism 8, engaging holes are respectively formed in the under surfaces of the rear end parts of a pair of right and left floor frames 7 extending along a longitudinal direction and mounted on the under surface of a floor panel 6. Hooks 10 pointing to above are respectively arranged in the positions, corresponding to the engaging holes, of the rear arch 3. Protrusions protruding to a front and a rear are formed on the tip parts of the hooks 10 and by thrusting the hook in the engaging hole from below with a given gap therebetween for holding in the operating state of the lock mechanism 8, deformation of the cab 2 and the rear arch 3 due to a load exerted in a longitudinal direction is suppressed. |
