摘要： PURPOSE:To prevent production of a burr, eliminate a remaining protrusion so as to reduce the size and weight by connecting a diffuser shell to a closure shell by means of electron beam welding. CONSTITUTION:A housing 1 is composed of a diffuser shell 2 and a closure shell 3, and the diffuser shell 2 is composed of a circular part 2a, central cylinder part 2b and inner cylinder part 2c. The central cylinder part 2b is provided with a caulking part 4 for fixing an ignition means and the inner cylinder part 2c accommodates a combustion means. The closure shell 3 is composed of an annular part 3a having a center hole 7 and a peripheral wall part 3b, and the peripheral wall part 3b is provided with a flange part 3c extending in the radial direction. A welded part 13 is formed in an outer peripheral part of the central cylinder part 2b and an outer peripheral edge part of the center hole 7; a welded part 14, at a tip part of the inner cylinder part 2c and in a region of the annular part 3a; and a welded part 15, at a peripheral edge part of the circular part 2a and a tip part of the peripheral wall part 3b. Since the welded parts 13, 14, 15 are electron beam welded, a remaining protrusion due to friction welding is not generated so as to miniaturize.

摘要： PURPOSE:To instantly ignite an unignited blasting cap even when it is present, and thereby prevent delay in ignition by providing a hole to communicate a transition explosive chamber with a blasting cap front face within a housing enclosure other than a blasting cap which communicates a blasting cap back face with the transition explosive chamber. CONSTITUTION:Energy transmitted in the reverse direction from a transition explosive chamber 9 through an additional hole (delayed ignition preventive hole) 32 directly reaches the thin piercing face 31 of a blasting cap 3 so that an unignited blasting cap 3 is instantly ignited with no delay in time. By this constitution, uncomfortable feeling due to sound by delay in ignition of the blasting cap 3 can thereby be eliminated.

摘要： PURPOSE:To reduce density with which combustion residue within gas is adhered onto a cut-out section, thereby enhance cooling effect by forming a circular gas cooling member which is interposed to a cooling member chamber provided for the outside of a gasifying agent chamber in the radial direction, into a shape in such a way that an inner lower portion of a cros section in the radial direction is cut out. CONSTITUTION:The bottom section of a gas generator container 13 is broken by gas or pressure built up by gasifying agent 21, after that, gas goes to the radial direction so as to go into a cooling member 14 in a cooling member chamber 10. In this case, the lower inner diameter side of the cooling member 14 is formed with a cut-out 15, to the surface of which residue is adhered. The surface area of the cooling member 14 is widened by the aforesaid cut-out 15, the amount of adhesion per unit area is thereby lessened so that gas flows smoothly. In addition, the cut-out allows gas to flow into the center section of the thickness of the cooling member 14 with no restriction while streaming in the shaft vertical direction, thereby enhancing cooling effect.

摘要： PURPOSE:To easily and surely perform fixing of a detonator irrespective of working accuracy of a detonator housing recessed part and to improve damp proofing effect for the detonator by using an elastic member as a detonator attaching an fixing means for a gas generator. CONSTITUTION:When a detonator 2 is inserted into a recessed part formed in an outer shell vessel 1 of a gas generator to fix it, an elastic member 11 is placed a gap between the detonator 2 and the recessed part of the gas generator to fix the detonator 2. A projective ring is formed on one end surface (a sensor side) of the elastic member 11 with a dimension and a constitution to satisfy damp proofing (airtight) function on press crushed when the sensor is assembled in.

摘要： PURPOSE:To restrict height of an inflator to low, and while obtain a large distance between an ignition bin and firing agent by arranging inflammation agent in a side of the firing agent to be arranged in the ignition direction of the ignition bin, and arranging gas generating agent in the surroundings of the inflammation agent and the firing agent. CONSTITUTION:In a mechanical ignition type inflator D, inflammation agent 13 is arranged in a side of firing agent 12 to be arranged in the ignition direction of an ignition bin 17b, and gas generating agent 14 is arranged in the surroundings of the inflammation agent 13 and the firing agent 12. Height of the inflator D can be therefore restricted to a height specified with an arrangement space of a starting device 17 and an arrangement space of the firing agent 12 and the inflammation agent 13, while a distance between the ignition bin 17b and the firing agent 12 can be made large within a height to be allowed by the inflator D. Consequently, collision energy of the ignition bin 17b against the firing agent 12 can be made large.

摘要： PROBLEM TO BE SOLVED: To make reutilization possible of an inflator total unit including powder, relating to an inflator for an air bag. SOLUTION: An inflator 10 is provided with a gas generating vessel, 12. In the inside of the gas generating vessel 12, powder of enhancer 40, automatic ignition agent 44, gas generating agent 46, etc., is received. The enhancer 40 is ignited by a squib 30, by flame thereof, the gas generating agent 46 is ignited, so as to release nitrogen gas. In a lower bottom part of the gas generating vessel 12, a sub-chamber 66 is provided. The sub-chamber 66 receives nitrocellulose which is the automatic ignition agent 44. When a vehicle is disused, unless powder in the sub-chamber 66 is deteriorated, the inflator 10 is judged able to reutilize it.
