Abstract

PURPOSE: To prevent the occurrence of a one-sided brake at high speed traveling time by constituting so as to stop actuation of an alarm device at lock condition time of brake pedals by a brake pedal left-right connection detecting switch. CONSTITUTION: When a high speed condition is detected by an auxiliary speed change switch 2 or a car speed sensor 3, an alarm device of a lamp 6 or a buzzer 7 is actuated through a controller 1, and it is reported to an operator. A solenoid 5 is actuated, and a lock member 10 is projected by actuation of its solenoid 5, and is locked on a hook member 11 of a right brake pedal 9, and left and right brake pedals 8 and 9 are locked. Therefore, a one-sided brake is not caused at high speed traveling time, and an accident such as an overturn can be prevented. When the brake pedals are locked, a brake pedal left-right connection detecting switch 4 operates, and actuation of the lamp 6 or the buzzer 7 is stopped, and the fact that a lock device operates is reported to the operator.
