Abstract: PURPOSE:To reduce both bending and torsion extents in a pedal operating member, by supporting the pedal operating member with an arm device, in case of a device which operates an accelerator and a brake by means of tilting operations of a manual control level frontward or rearward via the pedal operating member. CONSTITUTION:In a state that a brake locker 13 is released free, if a control lever 9 is operated to tilt rearward, a pedal operating member 31 is turned round to the rear of a link 33.
