Structure of a clockwork mechanism

摘要

The structure (1) has a fixed single-piece structure (11) including a fixed single-piece frame (17) with pivoting housings (12), which are aligned in pairs for receiving pivots of a pivoting mobile unit (10). A cover is irreversibly fixed on the frame after assembly of the mobile unit. The cover cooperates with the frame to confine a shaft (47) of the pivoting mobile unit with a clearance in a closure position of the cover on the frame. A resilient shock absorber is integrally formed with the fixed single-piece frame.
