However, when the auxiliary magnet 9 faces in a direction parallel to the auxiliary magnet 10, the auxiliary magnet 9 is locked to the hook 30 and temporarily fixed. It has become. As shown in FIG. 6, when the first member 2 and the second member 3 are arranged so as to be magnetically attached by the attraction magnet 8 via the glass 1, the auxiliary magnet 9,
If the polarity of 10 is set in the direction of magnetic adhesion, when the thickness of the glass 1 is large, the auxiliary members 9 and 10 can be magnetically attached to prevent the second member 3 from coming off. On the contrary, when the glass 1 is thin, if the polarities of the auxiliary magnets 9 and 10 are repelled,
The first member 2 and the second member 3 can be magnetically bonded with a magnetic bonding force that is not stronger than necessary. That is, when the thickness of the window glass 1 or the like is large, the rotation operation unit 11 is operated to operate the auxiliary magnets 9 and 1.
The first member 2 and the second member 3
Can be magnetically adhered so as not to come off with a magnetic force of a certain level or more, and when the thickness of the window glass 1 is thin, the rotation operation unit 11 is operated.
