1. A glass breakage detecting apparatus, comprising:
- a strain gage including an attaching portion and a strain detecting portion,the attaching portion being attached to an attached portion, the attached portion being at least one of an opening and closing mechanism, which freely movably supports a window glass within a door, and an inner panel of the door to which the opening and closing mechanism is arranged within the door;
the strain detecting portion for detecting a change in strain at the attaching portion; and
a glass breakage detecting device determining whether or not a breakage of the window glass occurs on the basis of the change in strain detected by the strain detecting portion while the opening and closing mechanism is being inactive.

Abstract
A glass breakage detecting sensor includes a strain detecting portion by which breakage of a window glass, which is provided at a door of a vehicle, is detected based on changes of an amount of strain, and an attaching portion attached to at least one of an opening and closing mechanism, which freely movably supports the window glass, and an inner panel to which the opening and closing mechanism is arranged within the door, the opening and closing mechanism and the inner panel functioning as an attached portion.

16. A glass breakage detecting apparatus, comprising:
-
a strain detecting portion by which strain of an attached portion is detected, and the strain detecting portion being attached to at least one of an opening and closing mechanism, which freely movably supports the window glass within a door, and an inner panel to which the opening and closing mechanism is arranged within the door, the opening and closing mechanism and the inner panel functioning as an attached portion; and a breakage determining portion determining a breakage of the window glass on the basis of a change in strain generated on the attached portion detected by the strain detecting portion while the opening and closing mechanism is being inactive.

17. A glass breakage detecting apparatus, comprising:
-
a strain generating body generating strain in cooperation with an attached portion when a window glass is raised to fully close a window, a strain generating body is attached to at least one of an opening and closing mechanism, which freely movably supports the window glass provided at a door of a vehicle, and an inner panel to which the opening and closing mechanism arranged within the door, the opening and closing mechanism and the inner panel functioning as an attached portion; a strain detecting portion outputting a detecting signal indicating an amount of strain generated on the strain generating body while the opening and closing mechanism is being inactive; a first fixing portion provided on one end portion of the strain generating body and a second fixing portion provided on the other end portion of the strain generating body for fixing the strain generating body with the attached portion; and restraining means for restraining the strain generating body such that straining directions of the strain generating body when the window glass is opened and closed, respectively, are made same.
