PROBLEM TO BE SOLVED: To provide a pilot relay which can remove or reduce a dead zone to improve a characteristic. SOLUTION: This pilot relay, provided with an air supply pressure chamber 7, output pressure chamber 5, air supply valve seat 11 communicating these chambers 5 and 7, air supply valve element 9 provided in the air supply valve seat 11, and a bleed hole 14 communicating the chambers 5 and 7, has a tensile spring 21 provided between the air supply valve element 9 and a body 2 to be formed so as to reduce force of the air supply valve element 9 pressed to the air supply valve seat 11 when a device is operated so that a value of a dead zone generated in the case of opening an air supply valve of the air supply valve seat 11 and the air supply valve element 9 can be reduced or eliminated.
