PURPOSE:To obtain a small-sized interlocking device free from the operation disorder by allowing an interlocking plale to shift only in the longitudinal direction and allowing the shift in unidimensional form. CONSTITUTION:As for the interlocking device for a speed change gear, the peripheral grooves 11a, 12a, and 13a formed on a plurality of forkshafts 11, 12, and 13 which are arranged in parallel and assembled in slidable manner in the axial direction on a case 14 can be engaged and disengaged with a single interlocking plate 31 assembled on the case 14, and when one forkshaft shifts in the axial direction, the shift in the axial direction of the rest forkshaft is suppressed. The interlock plate 13 can be shifted only in the direction in a plane crossing at right angle with each forkshaft axis line, and a plurality of tongue pieces 31a and 31b which are engaged with one of the peripheral grooves formed on the forkshafts 11, 12, and 12, 13 which are contiguous each other are formed on the plate 31, and an actual piece 31d which overlaps with an installation hole 14c is formed integrally on the plate 31. |
