To make it possible to change a travel speed by changing speed of a travel driving wheel without complicating a power transmission mechanism inside a mission case in a work machine that drives a work device and the travel driving wheel with power distributed inside the mission case.SOLUTION: In a travel speed changer for a work machine that travels by transmitting output of an engine 11 mounted on a travel vehicle body 10 to a work device 19 from a mission case 12, and further, transmitting the same to a travel driving wheel 14 through a travel transmission case 20, the travel transmission case 20 is provided with a speed changing mechanism 36 for speed-changing power from the mission case 12, and drive of the travel driving wheel 14 is speed-changed by the speed changing mechanism 36 to change a travel speed.SELECTED DRAWING: Figure 3

    【課題】本発明は、作業装置と走行駆動輪をミッションケース内で分配した動力で駆動する作業機において、ミッションケース内の動力伝動機構を複雑にすることなく走行駆動輪を変速して走行速度を変更できるようにすることを課題とする。【解決手段】走行車体10に搭載するエンジン11の出力をミッションケース12から作業装置19に伝動し、さらに走行伝動ケース20を通して走行駆動輪14に伝動して走行する作業機の走行速度変速装置において、走行伝動ケース20にミッションケース12からの動力を変速する変速機構36を設け、該変速機構36で走行駆動輪14の駆動を変速して走行速度を変えることを特徴とする作業機の走行速度変速装置とする。【選択図】図3
