TRANSMISSION FOR WORKING VEHICLE

To provide a transmission for a working vehicle which allows shortening of the axial length of a driven shaft while maintaining gear main items.SOLUTION: A transmission 1 for a working vehicle includes a stepped transmission mechanism 30 for changing the speed of prime motor power and transmitting it to an axle. The stepped transmission mechanism 30 includes: a plurality of gear change shafts 12b, 13b; an output shaft 14 driven by power from the gear change shafts 12b, 13b; and a second gear speed clutch shifter 43 which engages with a second gear speed output gear 41, which is at least one driven gear on the output shaft 14, so as to be relatively non-rotatable. A shifter claw part 43a is engaged with the second gear speed clutch shifter 43 so as to be relatively non-rotatable. A fixed claw part 41a is formed in a portion of the second gear speed output gear 41 that lies opposite the second gear speed clutch shifter 43 side. A third gear speed output gear 42, which is a shifter linkage gear that rotates at the same speed as the shifter claw part 43a, is arranged between the shifter claw part 43a and the second gear speed output gear 41, the shifter claw part 43a being positioned so as to penetrate the third gear speed output gear 42.SELECTED DRAWING: Figure 1 【課題】ギヤ要目を維持しつつ、被駆動軸の軸長の短縮化を行うことができる作業車用変速装置を提供する。【解決手段】原動機動力を変速して車軸に伝達する有段変速機構３０を備えた作業車用変速装置１において、有段変速機構３０には、複数の変速軸１２ｂ・１３ｂと、変速軸１２ｂ・１３ｂからの動力により駆動する出力軸１４と、出力軸１４上で少なくとも一つの従動ギヤである２速出力ギヤ４１と相対回転不能に係合する２速クラッチシフタ４３と、を備え、２速クラッチシフタ４３にはシフタ爪部４３ａが相対回転不能に係合されており、２速出力ギヤ４１の２速クラッチシフタ４３側に対向する部分には、固定爪部４１ａが形成されており、シフタ爪部４３ａと２速出力ギヤ４１との間にシフタ爪部４３ａと同一速度で回転するシフタ連動ギヤである３速出力ギヤ４２を配置し、シフタ爪部４３ａは、３速出力ギヤ４２を貫通するように配置される。【選択図】図１
