PROBLEM TO BE SOLVED: To provide an elastic center apparatus applicable also to fitting work of interference fit. SOLUTION: Three columnar limiters 5 of equal height are erected in the phase of 120 deg. around an axis C on the upper face of a lower structure body 3. When prescribed elastic displacement is vertically generated to each elastic body 4, the abutting bearing surface of each limiter 5 is received by the receiving bearing surface of a bracket mounted to the upper face 2a of an upper structure body 2. Consequently, when the prescribed elastic displacement is generated to the elastic body 4 with initial press-in force, the press-in force is supported by each limiter 5 to regulate the elastic displacement of the elastic body 4, and the press-in force is supported by three limiters 5 to maintain the parallelism of the upper structure body 2 and lower structure body 3 connected by the elastic bodies 4. Fitting work of smooth interference fit can thereby be carried out even when large press-in force is applied, besides securing a function of correcting eccentricity and inclination between parts by the elastic center apparatus 1. |
