GAS GENERATOR FITTING PART STRUCTURE, SEAT BELT DEVICE, GAS GENERATOR FITTING METHOD AND WEBBING WINDER MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2021049855
Kind Code:
A
Abstract:
To suppress such a situation in which an area of contact between a jig receiving a load, which is inputted to a gas conduit from a caulking punch, and the gas conduit, becomes narrow.SOLUTION: A gas generator fitting part structure comprises a gas generator 28, and a cylinder 30 to which the gas generator 28 is fitted. The cylinder 30 has: a first cylindrical part 34 which is formed into a cylindrical shape, and into which a gas generated by the gas generator 28 is supplied; and a second cylindrical part 36 which is connected to the first cylindrical part 34, of which a side opposite to the first cylindrical part 34 is opened, and of which an inner diameter and an outer diameter are so as to be larger than an inner diameter and an outer diameter of the first cylindrical part. In the state an end of the second cylindrical part 36 on a side opposite to the first cylindrical part 34 is folded to an inner side in a radial direction, the gas cylinder 28 is fitted to the cylinder 30. A radial thickness T2 of the second cylindrical part 36 on the first cylindrical part 34 side is thicker than a radial thickness T1 of the first cylindrical part 34.SELECTED DRAWING: Figure 4
