1. A fixing device for installing a pressure-type airbag sensor, the fixing device comprising:
a holder having a disk shape;
a cover coupled to the holder and having a sensor unit disposed at an upper end thereof; and
a connector housing disposed at a lower end of the cover,
wherein the holder comprises:
a holder body formed in a disc shape,
an outer wall having a predetermined height and formed on an outer circumference of the holder body,
a seal having a ring shape is insert-injected into the holder body to have a predetermined radius, and
protrusion parts having a predetermined curvature are formed on an upper surface and a lower surface of the holder body,
wherein
a height of the protrusion parts is lower than a height of the seal,
the holder body is configured to rotate relative to the cover, and
the seal forms sealing between the holder body and the cover, and
wherein
while the cover rotates, one surface of the cover comes into physical contact with a section in which the protrusion parts are formed and lifted by the height of the protrusion parts, and
when the cover passes through the section of the protrusion parts and is rotated to a set fastening position, the one surface of the cover is separated from the protrusion parts and returns to its original position.
