To provide a glass plate holding structure capable of suppressing the intrusion of noise from a glass plate attached to an opening of a vehicle or a building.SOLUTION: A glass plate holding structure for holding a glass plate 2 to be attached to an opening of a vehicle or a building is a laminated structure having a pair of viscoelastic layers 3a and a metallic layer 3b interposed between the pair of viscoelastic layers 3a, and has a damping member 3 abutting on a part of the glass plate 2. The metallic layer 3b is 50% or less of the total of the damping member 3 in thickness. The viscoelastic layer 3a has a loss tangent (tan δ) of 0.50 or more and 5.00 or less at 25°C and a frequency of 100 Hz to 10000 Hz, and a storage modulus G' of 1.0×10 6 or less at 25°C and a frequency of 1 Hz.SELECTED DRAWING: Figure 1

    【課題】乗物や建物の開口部に取り付けられたガラス板からの騒音の侵入を抑制できるガラス板保持構造を提供する。【解決手段】乗物または建物の開口部に取り付けられるガラス板2を保持するガラス板保持構造が、1対の粘弾性体層3aと、1対の粘弾性体層3aの間に介在する金属層3bと、を有する積層構造であり、ガラス板2の一部に当接する制振部材3を有する。金属層3bの厚さは制振部材3の総厚さの50%以下である。粘弾性体層3aは、25℃で周波数100Hz~10000Hzにおける損失正接(tanδ)が0.50以上5.00以下であり、25℃で周波数1Hzにおける貯蔵弾性率G’が1.0×106以下である。【選択図】図1
