As described above, the handle 1 and the lever 6 in the vehicle outdoor handle are connected by fitting one end of the lever 6 into the fitting recess 1d formed in the handle 1. The fitting relationship between the lever 6 and the handle 1 has a certain amount of clearance (clearance) in consideration of ease of assembly.
It has.

When the handle 1 is opened and released, the handle 1 returns to its original position by the return spring force of the lever 6, but there is a certain gap between the lever 6 and the handle 1 as described above. Due to the reaction when the lever 6 returns, the lever 6 vibrates within that range, and a vibration sound is generated between the lever 6 and the handle 1. In the case where the counterweight 8 for preventing the door from opening due to a side collision is attached to the other end of the lever 6, the vibration of the lever 6 is further increased, and the vibration noise is also increased.

Therefore, in the apparatus of the present invention, as shown in FIG. 4, a U-shaped groove 9 is formed at the front of the side wall of the connecting arm 1c of the handle 1, and the U-shaped groove 9 is formed at the lower end of the lever 6. A lever boss 6a to be fitted is protruded. And FIG.
As shown in FIG. 6, with the rotation of the lever 6 following the opening and closing operation of the handle 1, the lever boss 6a remains in contact with the contact surface T1 on one side of the U-shaped groove 9 so that the U-shaped groove 9 The inside can be slid downward. When the lever 6 returns to the steering wheel, the boss 6a is located between both side surfaces of the U-shaped groove 9 even if the lever 6 attempts to make a large amplitude due to the reaction.
Since the displacement of the lever 6 is suppressed by contact with the lever 2, the swing width of the lever 6 becomes extremely small, whereby the vibration can be suppressed and the rattling noise can be reduced. In other words, the engaging portion between the lever 6 and the handle 1 is provided with the restricting portion S for restricting the displacement due to the recoil when the lever 6 returns to the original position.

Here, the width dimension a of the U-shaped groove 9 is formed slightly larger than the diameter b of the lever boss 6a. Ideally, it is better that there is no gap between the lever boss 6a and the U-shaped groove 9. However, in practice, it is preferable to consider the dimensional variation of the members.
About 5mm must be left, so U
By setting the contact surface T1 of the character groove 9 as a reference surface for contacting the lever boss 6a, a variation in an assembling position causes
Even if the boss 6a moves up and down, the gap can be kept constant. As described above, by forming the boss 6a in a circular shape, the gap can be managed only by defining the diameter of the boss 6a and the dimension from the engagement surface on the handle side to the regulating surface. There is no interference between the six.

FIG. 7 shows another embodiment of the regulating portion according to the present invention, in which a projection 12 is provided at a position facing an abutting end of the lever 6 in an initial state. That is, the protrusion 12 comes into contact with the fitting recess 1d in the reaction direction when the handle is returned, so that the swing width of the lever 6 itself can be restricted to a very small value. Actually handle 1 and lever 6
It is necessary to leave a gap of about 0.5 mm between the protrusion 12 and the fitting recess 1d in consideration of the variation in the assembling accuracy.

FIG. 8 shows the projection 12 formed in an elastically deformable band shape. Ideally, there is no gap between the lever 6 and the handle 1. However, as described above, in practice, it is necessary to leave a gap of about 0.5 mm in consideration of the dimensional variation of the members. However, by forming the projection 12 elastically deformable in this manner, the dimensional variation can be absorbed, and the lever 6 and the handle 1 can be brought into contact with each other in the initial state.

Although the embodiment of the present invention has been described in detail, the gist of the present invention is that the unlocking member (lever) is located at the original position at the engagement portion between the unlocking member (lever) and the handle. The present invention is not limited to the above-described embodiment but includes a restricting portion for restricting the displacement of the unlocking operation member (lever) caused by the recoil when returning to the state described above. Various design changes can be made without departing from the above.

[0026]

As described above, the present invention has the following excellent effects. (1) Displacement of the unlocking operation member (lever) caused by the reaction when the unlocking operation member (lever) returns to the original position is restricted at the engagement portion between the unlocking operation member (lever) and the handle. Since the restricting portion is provided, the vibration of the unlocking member (lever) at the time of returning the handle can be suppressed, and the collision noise between the unlocking member (lever) and the handle can be reduced. (2) A boss is formed at the end of the unlocking operation member (lever),
A U-shaped groove having a regulating surface with which the boss abuts in the reaction direction at the time of lever return is formed on the handle side, and the width of the U-shaped groove is formed slightly larger than the diameter of the lever boss,
Since the contact surface of the U-shaped groove is used as a reference surface for contacting the lever boss, the gap can be kept constant even if the boss moves up and down due to variation in the assembling position. (3) Since a projection is provided at the end of the unlocking operation member (lever), and when the unlocking operation member (lever) returns, the regulating surface on which the projection abuts in the reaction direction is provided on the handle side. The amplitude of the unlocking member (lever) at the time of return can be restricted to a very small value, and the collision sound between the unlocking member (lever) and the handle can be reduced. (4) Since the protrusion at the end of the unlocking operation member (lever) is provided so as to be elastically deformable, the unlocking operation member (lever) and the handle can be brought into contact with each other in an initial state, and the assembling accuracy varies. Can prevent interference between the handle and the lever.
