ABSTRACT:
A high-voltage generating device generating a high-voltage in response to impartation of an impact to a piezo-electric element, in which an inner casing accommodating therein a hammer for imparting the impact to the piezo-electric element and a hammer spring for imparting a drive force to the hammer is telescopically received in an outer casing of an electrical insulator accommodating the piezo-electric element therein, and a return spring is disposed within the outer casing for normally biasing the inner casing in a return direction in which the inner casing protrudes from the outer casing. In the device, a conductive strip is pressed at one end thereof against the conductive driven member by the return spring and is exposed at the other end thereof to the exterior of the outer casing. The high-voltage generating device can be very easily assembled and can operate with improved characteristics including a stabilized output voltage characteristic, because of the fact that the piezo-electric element is pre-stressed by the return spring. In addition, a grounding connection can be very easily provided.
