Japanese Utility Model Publication No. 5-47225 discloses an automobile door lock knob in which a door handle and a lock knob are attached to an escutcheon by a shaft in parallel.

[0004]

By the way, in the door handle device disclosed in the above publication, the lock device operated by the lock knob is held at the lock position or the unlock position. No pressing force is applied to. Therefore, rattling noise may be generated when the automobile is running due to dimensional variation during mass production or shrinkage due to temperature change, which may give discomfort to the occupant. Therefore, as shown in FIG. 6, there has been proposed an inside door handle device for an automobile in which a leaf spring is provided between a door handle and a lock knob. This door handle device includes a base 1 having a pair of side walls 1a.
A shaft 2 mounted in a through hole 1b formed in each side wall 1a; a door handle 3 and a lock knob 4 pivotally mounted in parallel with the shaft 2; and a spring for urging the door handle 3 to a closed position. 5 is provided.

[0005] Although not shown, the base 1 is fixed to a door panel of an automobile by a known structure. The one end 2a of the shaft 2 is knurled and pressed into the through hole 1b, so that the shaft 2 is prevented from falling out of the through hole 1b. The door handle 3 has a substantially U-shaped cross section, and has through holes 3a and 3b through which the shaft 2 is inserted. A spring 5 wound around the shaft 2 is disposed inside the door handle 3 and urges the door handle 3 elastically inward.
The lock knob 4 also has a substantially U-shaped cross section, and has through holes 4a and 4b through which the shaft 2 is inserted. One end of a rod 6 is fitted into a through hole 3c formed in the door handle 3, and the other end of the rod 6 is operatively connected to a latch of a door lock device (not shown). One end of a rod 7 is fitted into a through hole 4c formed in the lock knob 4, and the other end of the rod 7 is operatively connected to a lock lever of a door lock device (not shown).

When the door handle 3 is manually operated against the elasticity of the spring 5, the latch of the door lock device can be operated via the rod 6. When the lock knob 4 is manually operated, the door lock device can be switched between a locked state and an unlocked state.
Since the door handle 3 is urged to the closed position by the spring 5, no backlash occurs. However, since the lock knob 4 is not provided with a spring, play may occur when the vehicle is running. In order to prevent the play of the lock knob 4, the cylindrical portion 8 a of the leaf spring 8 is disposed in the through hole 3 b of the door handle 3. The flange portion 8b formed at the end of the cylindrical portion 8a of the leaf spring 8 is disposed in the enlarged hole 4d of the through hole 4a of the lock knob 4. Since the flange portion 8b of the leaf spring 8 presses the lock knob 4 against the side wall 1a of the base 1 in a direction away from the door handle 3, play of the lock knob 4 can be prevented.

[0007] The leaf spring 8 is connected to the door handle 3 and the lock knob 4.
The method of preventing the play of the lock knob 4 by arranging the leaf springs 8 between them, increases the number of parts and also increases the number of assembly steps for mounting the leaf spring 8.

Therefore, the present invention does not increase the number of parts,
An object of the present invention is to provide an automobile door handle device that can prevent the play of the lock knob 4.
