CONSTITUTION:When the braking of a track 40 is applied in a car running condition, the a forward force by the inertia of a cab 42 is operated to a tilt cab suspension 43. When the forward force is operated to the tilt cab suspension 43, an upward force by a holding shaft 11 positioned in a rear side up position, and connection shafts 12 and 13 is operated to longitudinal frames 41 and 41 in the longitudinal direction of axes 36 and 37, and as a result, a nose dive of the cab 42 is suppressed.
