PROBLEM TO BE SOLVED: To provide a transmission device of a work machine not requiring a space for arranging a switching mechanism for switching a transmission mechanism on the basis of an operation of the operation lever, inside of a case, so that the case can be miniaturized.SOLUTION: A transmission device includes a transmission mechanism for changing rotational power from an engine and transmitting the same to an output shaft, a case for housing the transmission mechanism inside, an operation lever disposed outside of the case, a first shift fork for switching the transmission mechanism to a first gear shift state, a second shift fork for switching the transmission mechanism to a second gear shift state, a first operation mechanism having a first projecting portion projecting to the external of the case and operating the first shift fork, a second operation mechanism having a second projecting portion projecting to the external of the case and operating the second shift fork, and a switching mechanism capable of switching the operation lever to a first connection state connected to the first projecting portion and a second connection state connected to the second projecting portion, and disposed outside of the case.SELECTED DRAWING: Figure 1

    【課題】操作レバーの操作に基づいて変速機構を切り換える切換機構の配置スペースをケース内部に必要とせず、ケースを小型化できる作業機の変速装置を提供すること。【解決手段】エンジンからの回転動力を変速して出力軸に伝達する変速機構と、変速機構を内部に収容するケースと、ケースの外部に設けられた操作レバーと、変速機構を第1変速状態に切り換える第1シフトフォークと、変速機構を第2変速状態に切り換える第2シフトフォークと、ケースの外部に突出する第1突出部を有し且つ第1シフトフォークを操作する第1操作機構と、ケースの外部に突出する第2突出部を有し且つ第2シフトフォークを操作する第2操作機構と、操作レバーを、第1突出部に接続される第1接続状態と、第2突出部に接続される第2接続状態とに切り換え可能であって、且つケースの外部に設けられた切換機構と、を備えている。【選択図】図1
