ABSTRACT:
A shift control device in a hydrostatic continuously variable transmission in which a hydraulic closed circuit is formed between a swash plate type hydraulic pump and a swash plate type hydraulic motor, and a swash plate holder for supporting a motor swash plate of the hydraulic motor is tiltably supported on a stationary structure through a trunnion shaft fixedly mounted on the swash plate, wherein a drive shaft of a reversible electric motor is connected to the trunnion shaft through a reduction device which is constructed so that it transmits the rotation of the electric motor to the trunnion shaft at a reduced speed, but is brought into a locked state upon receipt of a reverse load from the trunnion shaft. This enables light adjustment of the tilting angle of the motor swash plate by use of a small-sized electric motor and reliable holding of the motor swash plate in a position at any angle.
