  The unlocking wire is generally made of a steel wire, one end of which is coupled to a synthetic resin handle, and the other end is coupled to a locking mechanism. Conventionally, the handle and wire are joined by casting an end member at the end of the wire and forming an engagement hole (groove) on the handle (lock mechanism) side where the end member fits at a specific angle (phase). It was done. However, the casting structure of the end member is expensive and the end member may come off. There is also a structure in which the end of the wire is passed through a hole formed in the handle and then folded back, but the workability is poor.

  An object of the present invention is to obtain a wire coupling handle capable of coupling a synthetic resin handle and a wire with high coupling strength by a simple coupling operation based on the above problem awareness.

The present invention provides a wire coupling handle for coupling an end portion of a flexible wire to a handle made of a synthetic resin, and an annular portion is formed on the end portion of the wire via a caulking member having a diameter larger than that of the wire. an annular space was hooking portion hooked the annulus of the heart can be inserted an annular portion of the wire, communicating with the annular space, forming a insertable tubular portion the caulking member, the In the annular space, a hooking projection for hooking the annular portion of the wire is projected on the opposite side of the tubular portion, and the wire is inserted into the tubular portion from a direction perpendicular to the extending direction thereof. The caulking member that can be inserted into and removed from the cylindrical portion is formed with a notch having a width that cannot be inserted and removed.

  The handle and the annular space are formed in a line-symmetric shape with respect to a virtual line segment connecting the tubular portion and the latching protrusion, and the retaining protrusion of the wire is formed to protrude in both sides of the virtual line segment in the annular space. Good.

  The wire coupling handle of the present invention can be applied without regard to the connection destination of the wire. Specifically, for example, the wire coupling handle can be used for a mechanism for opening a lock mechanism of a vehicular trunk lid from the trunk room. That is, it is possible to connect the end of the wire opposite to the handle so as to release the lock when the handle is pulled from within the trunk room.

  For opening the trunk lid, the lock mechanism is preferably provided with a support guide made of synthetic resin for supporting the handle.

  In one aspect, the handle has, in order from its end, a symmetric shape with respect to the imaginary line segment, a narrow end, a middle portion wider than the narrow end, and a gripping portion wider than the middle portion. And a pair of support protrusions are formed on the narrow end portion at symmetrical positions with respect to the virtual line segment. The support guide is formed by removing a part of the left and right side walls of the cross-sectionally U-shaped section that is open on one side to hold the narrow end portion of the handle, and the pair of supports of the handle. A pair of support grooves into which the protrusions are fitted are provided.

  According to the wire coupling handle of the present invention, after the wire annular portion is fitted in the annular space of the handle, the wire is inserted into the cylindrical portion from the notch, and then the caulking portion of the wire is slid into the cylindrical portion. The wire and the handle can be coupled with each other, and a strong coupling strength can be obtained with a simple coupling operation.
