A gas generator (30) of a gas generating device (100) is held by a cover (34) within a housing (11) of a webbing pretensioner (10). The cover (34) defines therethrough a hammer pin insertion hole (35). The hammer pin insertion hole (35) has an inner diameter smaller than the outer diameter of a fastening member such as a self-tapping screw (39) or that of a tool such as a screw driver, which is to be employed upon assembly and/or mounting of the gas generating device (100). This has made it possible to avoid accidental insertion of the fastening member or the tool into the hammer pin insertion hole (35) in the course of the assembling or mounting work and hence, to prevent a detonator (33) of the gas generator (30) from being accidentally struck. <IMAGE> |
