ABSTRACT:
A mechanical ignition sensor which can reduce rotational resistance of a trigger lever. An inner periphery of a slit on the side of a spring is formed into an inclined surface which is an abutment surface with an outer peripheral side of the slit opened. An inclined surface of a slide holding portion is formed as a curved surface along a locus of rotation of an abutment leading end portion of the slide holding portion. An angle of inclination .alpha. 1 of an abutment leading end P of an inertial mass body with respect to an axial direction of the mechanical ignition sensor is set small such that only the abutment leading end P abuts against the inclined surface of the slide holding portion. As a result, sliding resistance between the inclined surface of the slit and the inclined surface of the slide holding portion. Further, an end portion of the spring is inserted into a ring groove having a semicircular cross-sectional configuration, formed at a transverse-directional central portion of an end surface of the inertial mass body.
