ローダの変速制御装置。[Claims for Utility Model Registration] (1) A shift lever that can be selectively switched to each of a plurality of gear positions, a control valve unit that switches a hydraulic oil path to be supplied to a hydraulic clutch of a transmission, and the shift lever. In a wheel loader equipped with a mechanical link mechanism that connects a lever and at least a speed gear switching spool of a control valve unit, and a cargo handling device operating lever that operates a hydraulically operated cargo handling device, the vehicle speed is set to the first gear. A manual gear shift switch that generates a switching command signal for forcibly switching the gear is provided at or near the upper end of the cargo handling device operating lever, and an actuator is provided to switch the mechanical link mechanism to a position corresponding to the first gear. 1. A speed change control device for a wheel loader, comprising: a control device operatively connected to a shift lever or a mechanical link mechanism, the control device receiving a switching command signal from the speed change switch to drive an actuator. (2) The speed change control device for a wheel loader according to claim 1, wherein the speed change switch is mounted so that its position can be adjusted.
