PURPOSE: To contrive simple construction by providing a rod spring which has spring force at the end of a holding member in order to enable approach and separation between a coil and an armature.
CONSTITUTION: An electromagnetic hook 76 consists of a coil 77, a holding member 200 which holds the coil 77 and an armature 201. The member 200 includes a bottom plate 202 and side plates 203W205. At the end of the side plate 205, a projection 206 is formed and there holes 208 are provided. The armature 201 includes a base plate 209 and free end portion 210. The base plate 209 has a stepped portion 209a where a slit 211 is provided. After the projection 206 is inserted in the slit 211, the rod spring 207 is inserted in the holes 208 for fixing and the armature 201 can freely oscillate to the direction of arrow J around the center of the projection 206. For this reason, simple construction can be contrived and the cost can be reduced.
