PROBLEM TO BE SOLVED: To enhance the connection strength of a glass plate face and beads and retain the strength for a long time by providing, at beads, a base end part near the glass plate end face and a bulged part continuously extending to the inner peripheral side in the glass plate face direction of the base end part, and joining the whole rear face of both parts to the glass plate face. SOLUTION: Beads 16 are constituted of the base end part 16a of the end face side of a plate glass 14a and a bulged part 16b continuously extending to the base end part 16a toward the inside in the glass plate face direction to form a hollow part 18 in the inside. The rear face of the base end part 16a and the bulged part 16b are joined to the glass plate face with an adhesive. When a double glazing 11 is fitted in a sash frame 17, the upper end of the sash frame 17 presses the back face of the bulged part 16b in which the hollow part 18 is formed, and the bulge part 16b is elastically deformed to the glass plate face side to securely hold the double glazing 11 in the sash frame 17. Since the joining width of the beads 16 and the glass plate face extends to the rear face of the bulged part 16b, the joining strength is large. There is no space between the plate glass and beads 16 to prevent penetration of rainwater and retain the joining strength for a long time. |
