PROBLEM TO BE SOLVED: To suppress formation of a reverse gear stage at the time of forward traveling. SOLUTION: A hydraulic circuit 4000 includes a B2D oil passage 4560 to which hydraulic pressure is supplied at the time of forming of a first gear stage, a B2R oil passage 4564 to which hydraulic pressure is supplied at the time of forming of the reverse gear stage, and a feedback oil passage 4562 branched from the B2D oil passage 4560. The B2D oil passage 4560 and the B2R oil passage 4564 are connected with a B2C oil passage 4566 via a check ball 4570. The B2C oil passage 4566 is connected with a servo of a B2 brake 3620. A feedback port 4514 of a B2 control valve 4500 is connected with the feedback oil passage 4562. COPYRIGHT: (C)2006,JPO&NCIPI |
