To provide a compressive-load adjuster in a tightly binding system satisfying various requirements to a miniaturization, a lighting, a labor saving, an eccentricity and a shape adaptation and its usage.

In the compressive-load distribution adjuster 2 in which extended blade surface sections (b) connected to both sides respectively, holding a curvature surface section (a), a connecting surface section (d) or a connecting section (e) or the curvature surface section (a) and the extended blade surface sections (b) connected to the section (a) are formed to an external surface and a compressive-load surface section (c) receiving compressive load is formed to an internal surface, the adjuster 2 is composed of a surface material 5 in which the curvature surface section (a), the extended blade surface sections (b) and the connecting surface section (d) or the connecting section (e) are connected integrally. The adjuster 2 is abutted on the corner section of an article to be tightly bound 1 and the article 1 is bound tightly by a tendon 3 from a periphery as the usage.
