Zusammenfassung:PROBLEM TO BE SOLVED: To improve the front field of view during the travel of a wheel type working vehicle having an underside boom by optimally setting a rocking range of a parallel linking mechanism. SOLUTION: The rocking range of the parallel linking mechanism of a parallel link type cab moving mechanism 20 is set so as to take a position in working where moving pivot points 24 and 29 lie at the back of fixed pivot points 22 and 27 and a position in travel where moving pivot points 24 and 29 lie forward beyond a perpendicular upper part of the fixed pivot points 22 and 27 and over the position in working.
