PURPOSE:To obtain a miniaturized high tension generating equipment having a high quality of dust proofing performance by a method wherein a coil spring is provided to outside of a sliding member, with the use of this mechanism the sliding member is arranged so as to be separated from the enclosed member. CONSTITUTION:A tabular coil-spring 10 is provided to outside of a sliding member 7. The tabular coil-spring 10 is mad to actuate in such a way that it expands and contracts in the axial centre direction between the space of the enclosed member 4 and the sliding member 7 so as to restore the sliding member 7, after having a shock of generating the high tension. According to this mechanism, it is possible to miniaturize the enclosed member 4 as well as to prevent a dust from invading into the coil-spring 10, being covered with the cum mechanism. |
