Abstract
A neutral biasing mechanism in a hydrostatic continuously variable transmission includes a plurality of springs attached so as to be spanned from a pivot arm to a base. The plurality of springs bias the pivot arm such that a roller is fitted into a cam portion. A variable spring configured such that a biasing force thereof can be changed and another spring that is different from the variable spring are provided as the plurality of springs. The variable spring and the other spring are arranged at separate positions in a state where attachment positions thereof in the pivot arm and the base are separate from each other.
