A transmission coupling (), especially a timepiece transmission coupling, for the mechanical linkage of at least one first part (A) of a first shaft at least movable in rotation about a first axis (A) to at least one second part (A) of a second shaft at least movable in rotation about a second axis (A), the first and second axes being parallel or substantially parallel, the transmission coupling including the at least one first part (A), the at least one second part (A), and at least a first elastic return system ('-) arranged so as to limit or cancel out the play between the at least one first part (A) and the at least one second part (A), and connecting the at least one first part (A) and the at least one second part (A).

Timepiece transmission coupling

Spring () for clock mechanism, the spring comprising a body () extending between a first end () of the spring and a second end () of the spring, the spring being intended to be connected mechanically to a housing at each of the first and second ends, the spring comprising, between the first and the second end, at least one member () intended to act by contact on an element () of the clock mechanism, characterized in that the body comprises a deformable zone () extending in a curve () and in that the curve comprises a first part () that is concave when viewed from the first end.

Spring for clock movement

Spring () for clock mechanism, the spring comprising a body () extending between a first end () of the spring and a second end () of the spring, the spring being intended to be mechanically connected to a housing at each of the first and second ends, the spring comprising, between the first and the second end, at least one member () intended to act by contact on an element of the clock mechanism.
