[0006]
Since the wire fixing plate is fixed to the handle base by a fixing means such as a screw or a rivet, the number of parts and the number of assembling steps are increased, and the manufacturing cost tends to be increased.
[0007]
The present invention has been made in view of such a conventional technology, and has a structure in which a wire as a driving force transmitting member is fixed to a fixing plate fixed to a handle base. It is an object of the present invention to provide a vehicle door unlocking device capable of reducing costs.
[0008]
[Means for Solving the Problems]

An engaging hole through which the hinge pin passes is provided to face the pin supporting hole.
[0009]
According to the first aspect of the present invention, since the hinge pin also functions as a fixing means of the fixing plate, it is not necessary to separately prepare a fixing means such as a screw, which leads to a reduction in the number of parts and a reduction in manufacturing cost.
[0010]
According to a second aspect of the present invention, in the vehicle door unlocking device of the first aspect, the hinge pin is fixed to the handle base by swaging.
[0011]
According to the second aspect of the invention, in addition to the effect of the first aspect, the hinge pin is caulked and fixed to the fixing plate, so that the structure is strong against vibration of the vehicle. In other words, for example, when the hinge pin is provided with a screw thread and the hinge pin is screwed and fixed to the handle base, the hinge pin becomes loose due to vibration of the vehicle unless a separate screw loosening prevention means is added, and the fixing plate is formed. There is a risk of wobbling. However, according to the second aspect of the present invention, since the caulking fixing structure is used, the hinge pin is not loosened even if there is vibration, and the structure is strong against vibration of the vehicle.
[0012]
According to a third aspect of the present invention, in the vehicle door unlocking device according to the first or second aspect, one of the locking portions of the handle base and the fixing plate is configured as a protrusion, The other engaging portion is configured as a circular fitting groove into which the protrusion is rotatably fitted, and the protrusion is inserted into the fitting groove from an insertion groove having one end opened and the other end communicating with the fitting groove. To this end, the projection is formed in a substantially cylindrical shape having substantially the same diameter as the fitting groove and having a partially cutout surface on its outer peripheral surface.
[0013]
According to the third aspect of the present invention, in addition to the effects of the first or second aspect, in the locking portion of the handle base and the fixing plate, one of the locking portions is formed as a protrusion, and the other is formed as a projection. The stopper is configured as a circular fitting groove into which the projection is rotatably fitted, and the projection is formed so that the projection can be inserted into the fitting groove from an insertion groove having one end opened and the other end communicating with the fitting groove. The fixing plate is characterized in that it is formed in a substantially columnar shape having substantially the same diameter as the fitting groove and having a partially cutout surface on its outer peripheral surface, so that the fixing plate is more stably mounted.
[0014]
In other words, according to the first or second aspect of the present invention, at least one of the fixing portions (projections and / or fitting grooves) of the fixing plate and the handle base is made flexible to facilitate attachment. However, in this case, by providing the locking portion with flexibility, the fixing plate may be weakened against vibration in the mounted state and the mounting stability of the fixed plate may be slightly reduced. However, according to the structure of the third aspect of the present invention, even if the locking portion (the projection and the fitting groove) is formed as a rigid body without having flexibility, it does not extend in the extending direction of the insertion groove. The projection is inserted into the fitting groove through the insertion groove with the notch of the projection along the notch, and only by rotating the fixing plate around the projection at the initial insertion position, the locking portions (the projection and the fitting Mating groove) can be fitted in a stable state. Therefore, the mounting stability of the fixing plate can be improved while maintaining the ease of mounting the fixing plate.
