手段が設けられていることを特徴とする作業用走
行車における走行変速装置。 The working traveling machine is equipped with a working part that can be moved up and down via an elevating mechanism, and is equipped with a traveling transmission mechanism that changes the power transmission from the engine side in a stepwise manner. A speed change mechanism is provided that automatically switches the travel transmission mechanism from a high speed change state to a low speed change state by interfering with the elevating mechanism when the working part rises above the target. 1. A traveling transmission device for a work traveling vehicle, characterized in that the traveling transmission device is provided with a flexible means that becomes free from the lifting and lowering mechanism after switching to the state.
