Conventional technology Conventionally, in a power window for an automobile, a system shown in Fig. 11 was used as a means for detecting that some object, such as a part of the body, was caught between the window frame and the window glass when the window glass was closed. As shown, it has been proposed that a band-shaped pressure switch 3 is attached to a window frame 1 so as to be close to the window glass 2 when it is closed, and many embodiments have been published. In this plan, even if the contact point of the strip-shaped pressure switch 3 is pressed, it is necessary that the contacts 3a and 3b conduct and electrically close the circuit, so the contact is reliable for all of the many contact points. To ensure durability, the entire contact point had to be plated with an expensive precious metal. Further, as shown in FIG. 12, there is a problem in that the pressure switch 3 may not be pressed depending on the state of the object 9 that is held.

In the structure of this embodiment, the closing force when the window glass 2 is completely closed is received by the supports 11, 12 of the string 4, and no force is applied to the string 4. Therefore, it is possible to completely distinguish between a case where the window glass 2 is completely closed and a case where the window glass 2 stops rising due to an object being caught. Furthermore, as shown in FIG. 12, even when the clamped object is tilted, force is always applied to the end surface of the glass 2, so that effective detection can be performed as a safety device with a simple configuration.
