PROBLEM TO BE SOLVED: To be able to secure safety by improving operability of speed change operation, enhancing operability at the time of returning a speed change operation member to a neutral position in particular and enhancing operability of the speed change operation during travelling at high speed.SOLUTION: A speed change operation device 10 of a travelling device 1 is configured to transmit output of an engine 2 to a wheel 5 through an HST 3, which is equipped with a holding mechanism 20 that holds a speed change operation member 11 of the HST 3 at a prescribed speed change position. The holding mechanism 20 comprises: a first holding body 22 that is supported movably in an operating direction with respect to a support body 21 and is held near the support body 21 by distributing power to an electromagnetic holding part 24; and a second holding body 23 that is supported to be movable in the operating direction with respect to the first holding body 22 and is held with respect to the first holding body 22 through a friction material 25, where the second holding body 23 is connected to the speed change operation member 11. The device further comprises a switch part 30 that switches between power distribution and non-power distribution of the electromagnetic holding part 24 according to travelling operation of the travelling device 1.SELECTED DRAWING: Figure 2

    【課題】変速操作の操作性を改善すること、特に、中立位置に戻す際の操作性を高めること、高速走行時の変速操作性を高めることで安全性を確保できるようにする。【解決手段】エンジン2の出力をHST3を介して車輪5に伝動する走行装置1の変速操作装置10であって、HST3の変速操作部材11を所定の変速位置に保持する保持機構20を備え、保持機構20は、支持体21に対して操作方向に移動自在に支持され、電磁保持部24への通電によって支持体21側に保持される第1保持体22と、第1保持体22に対して操作方向に移動自在に支持され、第1保持体22に対して摩擦材25を介して保持される第2保持体23とを備え、第2保持体23が変速操作部材11に連結され、走行装置1の走行操作に応じて、電磁保持部24の通電・非通電を切り替える切り替え部30を備える。【選択図】図2
