Abstract
A soot filter for the exhaust gas of a diesel engine comprises a filter body and a glow plug for thermally regenerating the filter body. At least one glow rod has a contact part that is spring-mounted at the glow rod in an axially displaceable fashion. Its face side which is averted from the glow plug shaft, therefore, protrudes beyond the free end of the glow rod and is pressed onto the face of the filter body.
