A percussion detecting apparatus capable of enhancing an effect of disturbance interception by intercepting a micro-vibration conveyed from a support frame. A pad member has a pad having a back-side surface to which a base is fixed, and a percussion sensor is disposed on a back-side surface of the base. The pad member is supported by a frame via fixing members integral with the pad member and intervening members made of silicon rubber. Vertical protrusions having different protrusion heights are formed on an upper surface of a flange of each intervening member, and horizontal protrusions are formed on an inner peripheral surface of a through-hole of each intervening member. When the pad member in an unstruck state, each fixing member is in contact with a corresponding one of the intervening members only at the vertical and horizontal protrusions of the intervening member.
