A rubber body as an elastic body for closure closes a gap between a partition plate in which a through-hole is formed and refrigeration piping inserted through the through-hole. The rubber body for closure includes a pressurized insertion receiving portion having formed therein an opening into which the refrigeration piping is pressed and inserted, the pressurized insertion receiving portion elastically pressing and contacting in a liquid-tight manner an external surface of the refrigeration piping; a fitting portion fitted in a liquid-tight manner the peripheral edge portion of the through-hole in a state in which an inner circumferential surface of the through-hole is elastically pressed; and a displacement allowance portion that closes a gap between the pressurized insertion receiving portion and the fitting portion, and to allow a relative displacement of the pressurized insertion receiving portion and the fitting portion in a direction parallel to the partition plate.
