Abstract: An adhesive member includes: a first pin portion to be inserted into a first hole formed in a first adherend member; a second pin portion which is to be inserted into a second hole formed in a second adherend member to be adhered to the first adherend member, and is formed coaxially with the first pin portion; and a flange portion which is formed using an adhesive, and is mounted to a side surface of the first pin portion or a side surface of the second pin portion in a flange shape.

Abstract: A crosslinked polymer having shape memorizing property, said crosslinked polymer being obtained by thermally reversibly crosslinking a base polymer composed of a blocked copolymer of an aromatic vinyl monomer and a conjugated diene monomer, the base polymer having a glass transition temperature of 70.degree. to 140.degree. C., and the glass transition temperature being higher than the dissociation temperature of the thermally reversible crosslinkage contained in the crosslinkage polymer.

Abstract: A level-variable supporting apparatus is provided, which is so constituted that: a reversible swelling and contractive substance, which, with a prescribed temperature defined as the boundary, absorbs a swelling solution and then swells at a range of temperature on one side and discharges the swelling solution and then contracts at a range of temperature on the other side, is contained in liquidtight container which is expandable and shrinkable in prescribed directions; a liquid guiding portion to supply the swelling solution to the container and discharge it from the container, and a heating means to heat the substance are provided; and the swelling and contraction of the substance due to the change in the temperature of the substance with the prescribed temperature as the boundary causes the container to expand and shrink in the prescribed directions, thus leading to the change of the supporting position of a supported object supported by the container.
