摘要： PROBLEM TO BE SOLVED: To provide a solenoid valve avoiding wear of a sleeve outer periphery resulted from lateral pressure by making a direction of resultant force of the lateral force acting on a sleeve the same when output hydraulic pressure is output and when not output.SOLUTION: The solenoid valve includes a feedback port 34 and an output port 26 at a part opposite to an input port 37 relative to the axis of the sleeve 22, and the sleeve includes a recess 31 provided to form a feedback oil passage 28, a seal part 27 provided to enclose the feedback oil passage and seal leaking oil, and a lateral pressure reducing groove 30 formed to let the oil leaked from the feedback oil path through the seal part flow outside a valve section. The solenoid valve is configured so that the lateral pressure reducing groove lets out oil to make the direction of resultant force of the lateral force acting on the sleeve the same when the output hydraulic pressure is output and when not output, and avoids a defect that the sleeve has wear or the like.
