る。(Embodiment) The details of the present invention will be described below with reference to the embodiment shown in FIG. (These embodiments correspond to the mounting structure of the front end portion 2b of the gas stay 2 shown in FIG. 4.) FIG. 1 is an embodiment of the present invention, in which the gas stay 40 is
The end fitting 42 is fixed to the front end 41a of the gas filled cylinder 41, and this is further fitted into the inner hole 44a of the connecting fitting 44 and fixed.
Then, the connecting fitting 44 is connected to the bolt 25 via the ball bearing 27.

外部へ放出される。In this structure, the ball 45 is locked at the mouth of the gas passage 42a of the end fitting 42 so that the gas filled in the gas filled cylinder 41 does not leak out. On the other hand, the inner hole 44a of the connecting fitting 44
In addition, a pressing rod 47 that is inserted into the gas passage 42a and faces the ball 45 is fixed. Therefore, when an impact load acts on the gas stay 40 in the axial direction, the end fitting 42 moves and is pushed into the inner hole 44a of the connecting fitting, and the relative pressing rod 47 is moved.
Moves in the gas passage 42a and pushes the ball 45 into the gas-filled cylinder 41 (in the G direction). The enclosed gas passes through the gas passage 42a, the inner hole 44a, the through hole 47a provided in the pressing rod 47, and the through hole 44b provided in the connecting fitting 44,
It is released to the outside.

く、安全が保証されるという利点がある。(Effects of the Invention) The present invention is configured as described above, and when an impact is applied, the end fittings are damaged (the fitting state is lost), and the enclosed gas is released to the outside. That is, since the gas pressure inside the gas stay is released, extension of the stay is prevented, and the occupant in front of the stay is not hit, and safety is guaranteed.
