ABSTRACT:
A setting-up apparatus of over-centering coil springs comprises a base plate having a first opening, an oscillating member having a second opening and journalled on the base plate so as to be displaced between a first position and a second position, a coil spring provided with a first leg engaged with said first opening and a second leg engaged with said second opening in order to hold said oscillating member at either one of said first position and the second position separated by a centering dead point of the oscillating member, and a communication opening communicated with said first opening. The communication opening is adapted to receive the first leg of the coil spring without compression of the coil spring when the second leg is engaged with the second opening which doesn't have the communication opening.
