    Abstract: A liquid sealed damper includes: an attachment portion attached to a peripheral portion of an opening of a vehicle or an opening and closing member for covering the opening; a contact portion to which an external force is input; an insulator configured to isolate vibration and connect the attachment portion and the contact portion; a main liquid chamber in which working liquid is sealed, the insulator serving as a wall portion of the main liquid chamber; an auxiliary liquid chamber divided from the main liquid chamber by a partition member and having a wall portion formed of a diaphragm; and an orifice passage formed in the partition member and communicating with the main liquid chamber and the auxiliary liquid chamber. The partition member has an inner gap in the shape of a recess, and a part of the diaphragm is inserted into the inner gap.

    Abstract: A sound insulating member includes a mass section and spring sections. The mass section is disposed so as to have a gap with respect to an outer panel which divides an internal space of a vehicle body and outside thereof, and includes at least a part which has a planar shaped form. The plurality of spring sections are disposed on the mass section at a side of the mass section facing an outer panel. Each of the spring sections has a hollow film member having airtightness and flexibility, and a gas sealed inside the film member. The film member has a first stepped section and a second stepped section that are formed in a stepped shape in an arrangement direction of the outer panel and the mass section.

    Abstract: A sound insulation structure includes a mass part and a plurality of spring parts. The mass part is arranged to be spaced from a compartment member that compartmentalizes an internal space of a structure body and an outside. At least part of the mass part has a flat surface shape. The spring part is arranged on a side facing the compartment member in the mass part. The spring part includes: a hollow film material having airtightness and flexibility; and a gas encapsulated within the film material. The film material includes a recess part on one surface which is at least one of surfaces on the compartment member side and the mass part side.
