To bring about a state in which a shift gear can be easily engaged with a speed change gear even when an end surface of the shift gear and an end surface of the speed change gear butt against each other, in a gear transmission that comprises a speed change part having the speed change gear for setting a variable speed level and the shift gear slidably provided for a rotary support shaft and operated to be engaged with/disengaged from the speed change gear and changing a speed of input power so as to output it from the rotary support shaft.SOLUTION: A transmission mechanism 20B for outputting power of a rotary support shaft 24 toward a travel device is provided. The transmission mechanism 20B is provided with a transmission accommodation part 80 that permits idling at a set rotation angle of the rotary support shaft 24.SELECTED DRAWING: Figure 6

    【課題】変速段設定用の変速ギヤと、回転支軸にスライド可能に設けられ、変速ギヤに係脱操作されるシフトギヤとを有し、入力された動力を変速して回転支軸から出力する変速部を備えられたギヤトランスミッションにおいて、シフトギヤと変速ギヤの端面同士が当たってもシフトギヤが変速ギヤに係合し易い状態にする。【解決手段】回転支軸24の動力を走行装置に向けて出力する伝動機構20Bが備えられている。伝動機構20Bに、回転支軸24の設定回転角での遊転を許容する伝動融通部80が設けられている。【選択図】図6
