WINDOW PLATE FOR VEHICLE
A window plate for vehicle includes a metallic member joined via a viscoelastic member on a surface of the window plate. The metallic member and the window plate are electrically connected.
1 . A window plate for vehicle comprising:
a metallic member joined via a viscoelastic member on a surface of the window plate, the metallic member and the window plate are electrically connected.
2 . The window plate for vehicle according to claim 1 ,
wherein the viscoelastic member has a conductivity.
3 . The window plate for vehicle according to claim 1 ,
wherein the viscoelastic member and the metallic member cover at least a part of an end portion of the window plate.
4 . The window plate for vehicle according to claim 1 ,
wherein the viscoelastic member and the metallic member are arranged only in an inner region of the window plate.
5 . The window plate for vehicle according to claim 1 ,
wherein the metallic member is provided with a protruding portion that protrudes from the metallic member in a thickness direction of the viscoelastic member, and
wherein the protruding portion contacts the window plate.
6 . The window plate for vehicle according to claim 1 ,
wherein the metallic member covers at least a part of an end portion of the viscoelastic member, and contacts the window plate.
7 . The window plate for vehicle according to claim 1 ,
wherein at least a part of the metallic member is joined to the window plate via a conductive adhesion layer.
8 . The window plate for vehicle according to claim 7 ,
wherein an elasticity fraction, defined by dividing elasticity of the conductive adhesion layer at a frequency of 100 Hz and at temperature of 20° C. by elasticity of the viscoelastic member at a frequency of 100 Hz and at temperature of 20° C., is 1.0 or more but 5.0 or less.
