摘要：: There is provided a gear shifting method of a multistage transmission in which gear shift of a main transmission and an auxiliary transmission is mechanically operated by operation of one shift lever, and in which operability is enhanced, a gear shifting operation device of the multistage transmission, and a vehicle having the same mounted thereon. The gear shifting operation device is configured to be provided with: a cam mechanism 20 that has a select operation output member 55 and a shift operation output member 56, which are separation mechanisms that separate, into shift operation and select operation for each direction, operation by operation of one shift lever 52 that moves along at least one H-shaped shift pattern 60, a first cam groove 23 that operates by the select operation, and operates a shift mechanism 30 for auxiliary transmission that shifts a shift fork F1 for auxiliary transmission, and a second cam groove that operates a select mechanism 40 that selects a target shift fork F1 or F2 from among the plurality of shift forks F1 and F2 for main transmission; and a shift mechanism 10 for main transmission that operates by the shift operation, and shifts the shift fork F1 or F2 for main transmission selected by the select operation.
