Document Type and Number:
WIPO Patent Application WO/2023/084826
Kind Code:
A1
Abstract:
Provided is a filter unit for gas generator comprising a filter and a filter housing which coaxially positions and fixes the filter in a filter storage space. The filter housing includes a first constraining end portion which is arranged as a closed surface at one end of the filter housing and constrains one end surface of the filter in the axial direction, a second constraining end portion which is arranged at the other end of the filter housing so as to surround a periphery of a gas inflow opening and constrains the other end surface of the filter in the axial direction, and a peripheral wall portion which connects between the first constraining end portion and the second constraining end portion, and includes a gas exhaust opening. The peripheral wall portion includes constraining peripheral wall portions which constrain a peripheral surface of the filter, and a non-constraining peripheral wall portion in which the gas exhaust opening is arranged and which is arranged apart from the peripheral surface of the filter such that there is an annular gap to the peripheral surface of the filter.
