Abstract
A transmission apparatus includes an interlock member having a restraining portion movable together with a shift and select member in a right-angled direction and, while fork heads are at neutral positions in the right-angled direction, extending in the right-angled direction along a notch of the tip end of each fork head. The restraining portion has a gap into which the tip end of each fork head extends. A dimensional relationship among an outer span of the tip end of each fork head, an inner span of the notch, an outer span of the restraining portion, an inner span of the restraining portion, a width of the tip end of the shift and select member, and a shift stroke of each fork head is set to be: H2−P1≧0; P2−H1+2S≧0; and H2−2S−I≧0.
