Human-body aimed spacer, human-body aimed airflow passage, and general-purpose spacer

Abstract

There is provided a human-body aimed spacer for restricting rugged feeling, which is flexible and light-weighted and requires only a smaller storage space. The spacer comprises a number of convex parts, and flexible connecting portions. The convex partseach comprises: a frame-like portionformed at a side contacting with a human body; four column portions, each having one end continuing to the frame-like portion, and each being formed to rise from the frame-like portion; and a rising-portion integratorfor interconnecting the other ends of the column portionswith one another. The flexible connecting portionseach interconnect adjacent ones of the frame-like portionswith each other. The spacer is configured to contact with a human body at the side where the frame-like portionsare formed, and to abut on a cushion or the like at the side where the rising-portion integrators are formed.
