Therefore, when the operator views the connection device 1 from the thickness direction, the free end 73 of the rotating member 71 can be easily visually recognized. That is, in the example shown in FIG. 26, when the operator can visually recognize the free end 73 of the rotating member 71 when viewing the connection device 1 from the thickness direction, the elastic member 4 is maintained in a non-connected state. It is judged that Also in the example illustrated in FIG. 26, the free end 73 of the rotating member 71 is the above-described identification unit.
- the elastic member 4 shifts from the non-connection state to the connection state when the release portion or the operation portion is pushed downward by the distal end portion of the electric wire 91, but the invention is not limited to this.
- the release portion or the operation portion is pushed sideways by the wire 91 and moved. Good.
- the force that bends the elastic member 4 is removed, and the elastic member 4 shifts from the non-connected state to the connected state.
- the release portion or the operation portion when the release portion or the operation portion is pulled by the electric wire 91 inserted between the terminal portion 3 and the elastic member 4, the force that bends the elastic member 4 is removed, and the elastic member 4 is not connected. You may move from the connection state to the connection state. Further, the releasing part or the operating part is rotated by rubbing the side part by the electric wire 91 inserted between the terminal part 3 and the elastic member 4, and the force for bending the elastic member 4 is removed, so that the elastic member is removed. 4 may shift from a non-connected state to a connected state.
- connection devices 1, 1a to 1f described above may be used for connecting electric wires in various devices.
- the connected devices 1 and 1a to 1f may be used as relay sockets or operation switches.
