    摘要: A shifting mechanism for a transmission having a plurality of gear ratios includes a first shaft (117) having a first axis X, a second shaft (118) having a second axis Y and traversing the first shaft to form a cross together, and a shift lever supported by the first shaft and second shaft to be rockable about the first axis X and second axis Y. A combination of rocking movement about the first axis X and rocking movement about the second axis Y of the shift lever determines one of gear ratios of the transmission. A first shift fork (47), a second shift fork (48) and a third shift fork (49) are provided for operating the transmission (2). The rocking movement about the first axis X of the shift lever (112) selects one of the first shift fork (47), second shift fork (48) and third shift fork (49). The selected shift fork (47, 48 or 49) is moved by the rocking movement about the second axis Y of the shift lever, to produce two gear ratios of the transmission.
