Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door outer handle device mounted on a vehicle. 2. Description of the Related Art Heretofore, there has been known a door outer handle device mounted on a vehicle in which a balance weight is attached to a handle. A door outer handle device of this type is disclosed in Japanese Utility Model Laid-Open No. 62-27961. FIG. 5 shows the structure of the door outer handle device described in this publication. According to this publication, a balance weight is attached to a handle arm of a vehicle door handle, and a mounting shaft 30e protruding through a mounting hole 45e provided in a handle arm 45 on one side surface of the balance weight 30. A balance weight mounting structure is described in which a sub weight 32 is inserted into the mounting shaft, and the end of the mounting shaft 30e is caulked to a side surface of the sub weight 32. In this publication, as a prior art, a mounting shaft 30e in which a balance weight 30 protrudes from one side is provided with a mounting hole 45e formed in a handle arm 45.
And a balance weight mounting structure that penetrates the handle arm 45 with its protruding portion is described. However, in the above-described balance weight mounting structure, since the handle arm is made of a non-metallic material (generally, a thermosetting resin), a mounting hole provided in the handle arm is provided. Is reduced in diameter due to heat shrinkage during molding, and is subsequently machined (eg, drilling)
In some cases, heat is generated during processing, so that the inner diameter after processing cannot be accurately maintained. Therefore, it is difficult to maintain the fitting between the mounting hole and the mounting shaft of the metal balance weight at a predetermined accuracy, and the following problem occurs. The mounting shaft of the balance weight is slightly thicker than the mounting hole of the handle arm, and is pressed into the mounting shaft of the handle arm and fixed without any gap. However, as described above, since the inner diameter of the mounting hole of the handle arm is not accurate,
If the mounting shaft of the balance weight is too thick for the mounting hole of the handle arm, the inner diameter of the mounting hole of the handle arm at the time of press-fitting is increased, or at the time of caulking the tip of the balance weight mounting shaft after press-fitting, the balance weight due to the caulking pressure Expansion of the outer diameter of the mounting shaft further increases the inner diameter of the mounting hole of the handle arm, so stress concentrates near the mounting hole of the resin handle arm and cracks occur, making it impossible to hold the balance weight. Become. On the other hand, when the balance weight mounting shaft is smaller in diameter than the handle arm mounting hole, a gap is created between the balance weight mounting shaft and the handle arm mounting hole, causing vibration when the vehicle runs or when the door is opened and closed. The impact causes the balance weight to rattle against the handle arm, generating abnormal noise. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to provide an error in the fitting between the mounting shaft of the balance weight and the mounting hole of the handle arm. Even if it occurs, an object of the present invention is to provide a door outer handle device in which an elastic member constituting a part of a mounting hole of a handle arm absorbs the error and can surely hold a balance weight. [0005] In order to solve the above-mentioned problems, the present invention takes the following means. The invention according to claim 1, wherein a handle rotatably supported by a door of the vehicle and connected to an opening / closing mechanism of the door, and an extended portion provided substantially symmetrically with respect to a handle portion of the handle centering on the shaft support portion. A balance weight mounting recess provided in the extension portion for holding the balance weight, and a rose having an outer diameter smaller than that of the weight portion.

The leading end of the spring presses the balance weight mounting recess with an urging force. As a result, the balance weight
It is not necessary to make the diameter of the balance weight fixing portion and the diameter of the balance weight mounting recess provided in the extension portion of the handle equal to each other. In addition, no crack is generated in the balance weight mounting recess, and the balance weight does not rattle with respect to the balance weight mounting recess. Further, since the handle is urged to the door by the return spring, the handle does not rattle against the door. Further, since the balance weight is urged by the distal end portion of the return spring to the balance weight mounting recess provided in the extending portion of the handle, an additional elastic member may not be provided. Therefore, the number of parts is not increased. Ma
In addition, since the shape of the balance weight is a shape in which axial movement is prevented when the balance weight is engaged with the recess for mounting the balance weight, processing such as caulking work is not required when assembling the handle device. The assembly operation is very simple. A first embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the door 11 of the vehicle includes a door inner panel (not shown), a door outer panel 12, and a frame 13. An opening 14 is formed in the door outer panel, and the door outer handle device 100 is attached to the opening 14. As shown in FIGS. 2 to 4, the handle device 100 is rotatably supported on the handle 41 by a handle 41, a shaft 60, and a shaft 60 for operating a door opening / closing mechanism (not shown). The handle case 23 is fixed to the door outer panel 12 with bolts, a return spring 80 (biasing means), and a balance weight 30. The handle case 23 includes a depression 26 serving as a frame of the handle handle portion 40, a through hole 23a through which the handle arm 45 penetrates from the vehicle exterior to the vehicle interior, and a shaft 6.
The handle case arm 23c which is pivotally supported by the handle arm 45 by 0 is provided. The handle 41 is rotatably supported by the handle case 23 by a shaft 60 while being penetrated through the through hole 23a of the handle case 23. The outside of the vehicle has a substantially flat plate shape and a handle handle portion. A handle arm 45 is formed integrally from the inner surface of the handle portion 40. The handle arm 45
Extends from the inside surface of the handle handle portion 40 to form an extended portion, and extends through the through hole 23a of the handle case 23 to the inside of the vehicle. A shaft hole 45b is provided inside the handle arm 45 and is rotatably supported on the handle case 23 by a shaft 60 passing through the shaft hole 45b. One of the two extended handle arms 45 is further extended, and a balance weight mounting recess 45a is formed at the tip thereof. When viewed from the front of the vehicle, the concave portion 45a for attaching a balance weight has substantially the same width as the outer diameter of the balance weight locking portion 30a provided on the balance weight 30, and is at least deeper than the outer diameter of the balance weight locking portion 30a. The recess is a recess that is wider than the outer diameter of the distal end of the return spring 80 when viewed from the side of the vehicle. The balance weight 30 has a weight 3
0b and the locking portion 30a, and the entire weight is substantially the same as the handle 41. The locking portion 30a has a smaller outer diameter than the weight portion 30b, and its axial length is the same as the cross-sectional width of the handle arm 45 when viewed from the side of the vehicle. 4
When engaged with 5a, movement in the axial direction is suppressed. The outer diameter and length of the weight portion 30b are appropriately determined, and the weight is set to be substantially the same as the handle 41 as a whole. The return spring 80 is axially penetrated by the shaft 60 through the coil winding. One end 80b of the coil winding is locked to the handle case 23, and the other end is a handle arm tip 80a (elastic). And a balance weight locking portion 30a attached to the tip of the handle arm 45 and extending toward the upper side of the handle arm 45 in an oblique direction from the vehicle upper side to the vehicle outer side. Balance weight locking part 30

It is fixed while being held down by the elastic force of the return spring tip 80a. Next, the operation of the first embodiment of the present invention will be described. In the first embodiment of the present invention, it is not necessary to precisely process the outer diameter of the locking portion 30a of the balance weight. Even if an error occurs in the outer diameter of the locking portion 30a of the balance weight, the amount of deformation of the distal end portion 80a of the return spring only changes in accordance with the outer diameter. It is urged toward the balance weight mounting recess 45a. Accordingly, no gap is generated between the balance weight 30 and the handle arm 45 due to vibration during vehicle running or impact when the door is opened and closed, so that the balance weight 30 does not rattle and generation of abnormal noise can be prevented. Further, when assembling the handle device 100, the locking portion 30a of the balance weight is engaged with the concave portion 45a for attaching the balance weight of the handle arm 45, and from above, the distal end portion 80a of the return spring is engaged with the balance weight. It only has to be hung on the stop 30a. Therefore, even if the handle arm 45 is made of resin, the return spring tip 80
