ABSTRACT:
The invention is directed to a pulse generator provided with a connecting member electrically connecting the lead and coil having an entwining section at one end thereof at the portion different from where an end of the coil is fixed, around which wound the middle portion of the coil drawn out to be connected to the lead, whereby a stress added to the drawn out coil is absorbed by the coil twined around the entwined portion, to be prevented from cutoffs of the coil fixed to the one end of the connecting member. A reinforcing member can be applied to the connecting member at an end thereof where the coil is fixed, to reinforce the bending strength of the end portion of the connecting member thereby to prevent cutoffs of the coil. Furthermore, the pulse generator may be provided with a bobbin having a protrusion at the edge of one flange thereof the drawn out coil twining around thereby to maintain the winding strength of the coil to facilitate the following work. In addition, the drawn out coil is prevented from being rubbed by the edge of the flange to be cut off.
