PROBLEM TO BE SOLVED: To provide twin-clutch type speed change gears having an interlocking function which prevents double engagement of gears and jumping-out of gears. SOLUTION: A plurality of fork heads 21A to 21D connected with a plurality of shift forks 25A to 25D selecting each speed change shift of the twin-clutch type speed change gears are provided with interlocking members 15, 15A, and 15B which forms notches 21c while respective pointed heads 21a are overlapped with each other and also form gaps 17 permitting passage of these pointed heads while the pointed heads are extended along the inner parts of respective notches so as to limit movements in their shifting directions. Respective dimensions of an outer width H1 of the pointed head of the fork head, an inner width H2 of the notch, an outer width P1 and an inner width P2 of a restriction part, the width I in pointed heads of shift and select members 18A and 18B, and a shift stroke S of the fork head are set to be H2-P1≥0, P2-H1+2S≥0, and H2-2S-I≥0.
