Abstract

The collet (1) has a flexible structure (2) elastically locking a rod (3) of a balance. The structure has sides (8) to be in contact with the rod. The sides have variable thickness such that maximum constraint exerted by the rod on the structure is lesser than the elastic limit of a material e.g. silicon, used for fabricating the structure. A rigidifying structure (4) surrounds the structure (2).
