FIELD: mechanical engineering and construction industry, particularly, eccentric units for installation of modules on vacuum body of thermonuclear reactor. SUBSTANCE: the essence of invention consists in that eccentric unit containing circular eccentric, support and hold-down part, is provided with external eccentric in form of disk with blind hole accommodating circular eccentric. Eccentricities of both eccentrics are equal in value. Support has flange which is secured by hold down part in sleeve installed in circular eccentric. Flange axis together with support axis forms acute angle. Sleeve cylindrical cavity is inclined relative to its axis and has inclination angle equaling the angle between axes of support and flange. EFFECT: higher reliability and accuracy of adjustment in installation of supports in assembly of large-size structures due to compensation of linear errors in dimensions and also in side misalignment of axes. 15 cl
