A percussive machine having an impact mechanism accommodated to a housing with a hammer piston imparting blows to a rock-destroying member. There is provided an air-supply duct for supplying compressed air to the impact mechanism and to the hole face. In order to prevent the machine from moving away from the hole face during the operation, the housing is provided with an elastic tubular member having a space in constant communication with the air supply duct.
