Conventionally, when starting an engine, it is known that the main clutch is disengaged or the transmission is returned to a neutral state to cut off power transmission to the traveling gear. Sometimes, it is easy to forget to perform the above operation in advance, which may lead to an accidental start of the vehicle when the engine is started, leading to an unexpected accident.

A safety device at the time of engine starting described in Publication No. 21447 has been proposed. What is described in this publication is that in a vehicle equipped with a hydraulically driven transmission, a safety switch is provided in the electric circuit for starting the engine separately from the starting switch, and the safety switch is connected to the hydraulically driven transmission. This is connected to a solenoid switch and a starter motor for controlling a bypass valve provided between a high-pressure side pipe and a low-pressure side pipe between the pump and motor.

The conventional safety device described above has a bypass valve installed between the high-pressure side pipe and the low-pressure side pipe of the oil passage between the pump and the motor, and a safety device installed separately from the starting switch on the solenoid for operating the bypass valve. Since we are trying to short-circuit the pressure oil supply between the pump and motor by connecting the switches in series, we will separately install a bypass valve, a solenoid to operate this bypass valve, and a safety switch to operate this solenoid in the conventional device. The number of parts increases, resulting in high costs, and the above-mentioned conventional type cannot be used at all for tractors having a clutch-type transmission mechanism.

The present invention aims to solve this problem.
