摘要

Ignition means (51, 61) are in combustion chambers (50, 60) provided in housing (3), one combustion chamber is provided in inner shell (4), ignition means disposed eccentrically to center axis of housing. Communication hole allows combustion chambers to communicate to each other, automatic igniting material, which is ignited and burned by conductive heat, is placed in combustion chamber. Limiting means specifying connection between ignition signal output means and ignitor (8) is provided in connector (10) attached to lead wire feeding ignition signals to ignitor, axial end faces of cylindrical filter means (50) have inclined face (51), and supporting member supporting inclined end face of filter means swiveled in radial direction due to pass of working gas installed in housing.
