PROBLEM TO BE SOLVED: To prevent falling into an unexpected situation by a sudden reverse travel and reversing with a working machine touching the ground while keeping an advantage that a switchover between a forward speed shifting state and a reverse speed shifting state can be continuously done and that a machine body operation can be done well. SOLUTION: A forward travel guide part FG and a reverse travel guide part BG of a traveling lever 51 are connected to a forward and reverse travel neutral guide part NG at guide base end parts thereof. The traveling lever 51 is energized to the base end part of the forward travel guide part FG by the forward and reverse travel neutral guide part NG. A switch SW is provided on a reverse travel guide part BG side end part of the forward and reverse travel neutral guide part NG. The switch SW detects movement of the traveling lever 51 to the reverse speed shifting operation side of the forward and reverse neutral guide part NG and the working machine 4 is raised.
