PROBLEM TO BE SOLVED: To provide a valve structure for a shock absorber capable of improving ride comfort of a vehicle even if piston speed reaches a high speed area. SOLUTION: This valve structure for the shock absorber includes a channel 7 providing communication between one chamber 41 and an upstream of a port 2a provided on a valve disk 1, a throttle valve 11 provided with a valve element 12 disposed in a middle of the channel 7 capable of reducing a channel area, and a leaf spring 25 applying a pressure of the one chamber 41 on the valve element 12 so as to generate thrust force in a direction reducing the channel area, applying a pressure of another chamber 42 or an intermediate pressure between the pressure of the one chamber 41 and the pressure of another chamber 42 so as to generate thrust force opposing to thrust force by the pressure of the one chamber 41, and biasing the valve element 12 in a direction opposing to the thrust force by the pressure of the one chamber 41, and makes the leaf spring 25 partially abut on the valve element 12 at a circumferential interval.
