The fixing plate and the handle base are provided with locking portions that are locked to each other at the mounting position of the fixing plate, and the hinge pin formed on the handle base at the mounting position of the fixing plate is provided on the fixing plate. A locking hole through which the hinge pin passes is provided opposite to the pin support hole.
[0009]
According to the first aspect of the present invention, since the hinge pin also serves as a fixing means for the fixing plate, there is no need 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 lock releasing device according to the first aspect, the hinge pin is caulked and fixed to the handle base.
[0011]
According to the invention described in claim 2, in addition to the effect of the invention described in claim 1, since the hinge pin is caulked and fixed to the fixing plate, the structure is strong against the vibration of the vehicle. In other words, for example, when the hinge pin is provided with a screw thread and the hinge pin is fixed to the handle base by screwing, unless the means for preventing the screw from loosening is added, the hinge pin is loosened due to the vibration of the vehicle, and the fixing plate is There is a risk of wobbling. However, according to the second aspect of the present invention, because of the caulking fixing structure, the hinge pin is not loosened even if there is vibration, and the structure is strong against the vibration of the vehicle.
[0012]
In the invention according to claim 3, in the vehicle door lock releasing device according to claim 1 or 2, one of the locking portions of the handle base and the fixing plate is configured as a protrusion, The other locking portion is configured as a circular fitting groove that fits the protrusion rotatably, and the protrusion can be inserted into the fitting groove from the insertion groove whose one end is open and the other end communicates with the fitting groove. Therefore, the projection is characterized by being configured as a substantially cylindrical shape having substantially the same diameter as the fitting groove and partially having a cutout surface on the outer peripheral surface thereof.
[0013]
According to the third aspect of the present invention, in addition to the effect of the first or second aspect of the invention, one of the locking portions of the handle base and the fixing plate is configured as a protrusion, and the other locking portion. The stop is configured as a circular fitting groove that fits the protrusion rotatably, and the protrusion is inserted into the fitting groove from the insertion groove with one end open and the other end communicating with the fitting groove. Since it is characterized by being configured as a substantially cylindrical shape having substantially the same diameter as the fitting groove and partially having a notch surface on the outer peripheral surface thereof, the mounting state of the fixing plate is more stable.
[0014]
In other words, according to the first or second aspect of the present invention, at least one of the locking portions (protrusions and / or fitting grooves) of the fixing plate and the handle base is made flexible so as to facilitate attachment. However, in this case, by providing the locking portion with flexibility, there is a possibility that the mounting stability of the fixing plate is slightly lowered because the fixing plate is weakened against vibration in the mounting state. However, according to the structure of the third aspect of the present invention, even if the locking portion (projection and fitting groove) is configured as a rigid body without having flexibility, the insertion portion extends in the extending direction. Insert the protrusion into the fitting groove through the insertion groove with the notched surface of the protrusion aligned, and rotate the fixed plate around the protrusion at the initial insertion position. Can be fitted in a stable state. Therefore, it is possible to improve the mounting stability of the fixed plate while maintaining the ease of mounting the fixed plate.
