Abstract
A high voltage generating device comprises an outer housing in which an abutment, a piezoelectric element and a receptacle member are housed, an inner housing slidably supported in a space within the outer housing and a hammer supported within the inner housing, said abutment being struck by said hammer to generate a high voltage. An inner peripheral surface of the outer housing is formed with a cam which is adapted to engage with and disengage from a pin mounted on the hammer in order to prevent impact noise generated when the abutment is struck from leaking outside the outer housing, whereby the high voltage generating device which generates small impact noise and which is protected from the entrance of dust is provided.
