Abstract
The balance includes at least two arms (1, 1') radially fixed to a pivoting staff (3). This staff is subjected to the action of return means consisting of two spring leaves (4, 4') each fixed in a radial slot made in a leaf-holder element (5). This leaf-holder element is drilled with a central orifice and is driven onto the pivoting staff. This balance can be used in any device having an element propelled with an oscillating movement, for example in order to regulate a mechanical movement. <IMAGE>
