PROBLEM TO BE SOLVED: To provide a valve structure capable of preventing delay in returning to the position to abut on a valve body of a leaf valve. SOLUTION: This valve structure is provided with the valve body 1 having a port 2, a rod 5 protruding from an axis part of the valve body 1, the annular leaf valve 10 having an inner peripheral side to which the rod 5 is inserted and placed on the valve body 1 so as to close the port 2, an energizing means 15 for energizing the leaf valve 10 to the direction of closing the port 2, and a stopper 25 formed to be in a bottomed cylindrical shape and arranged to have an aperture facing the leaf valve 10 side so that the leaf valve 10 resists the energizing force of the energizing means at the aperture and a retreat amount retreating from the valve body 1 is regulated. A communication hole 26a is provided in the stopper 25 in order to communicate an inside and an outside of the stopper 25 with each other, and a guide 20 is provided for guiding fluid from the outer side of the stopper 25 to the communication hole 26a.
