【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a handle device A according to the present invention. This handle device A is a so-called inside handle device, which is provided inside the vehicle door and is connected to a door lock device B (shown in FIG. 6) described later by a link wire 3 so as to interlock with each other. Such a handle device A includes a handle case 30, and a handle 8 and a lock knob 9 that are rotatably supported by the handle case 30. The handle 8 can be pulled and operated in the direction perpendicular to the paper surface of FIG. 1 against the spring force of a return spring (not shown). A handle lever 2 as an operating piece is provided which swings integrally with the handle 8 when operated. One end of a link wire 3 is connected to the handle lever 2 via a connecting device C according to the present invention.

As shown in FIGS. 2 and 3, the coupling device C locks a substantially L-shaped locking piece 1 provided at the end of the link wire 3 and the locking piece 1 to the handle lever 2. In this case, the fastener 7 is attached to the handle lever 2 in advance in order to firmly hold the locking piece 1. The locking piece 1 is composed of a first shaft portion 4 extending in the longitudinal direction of the link wire and a second shaft portion 5 that extends by bending from the tip of the first shaft portion 4. The fastener 7 is integrally molded of synthetic resin, and includes a grip portion 26 that grips the first shaft portion 4 of the locking piece 1, a tubular portion 27 into which the second shaft portion 5 of the locking piece 1 is inserted, and a hook. It has a moving surface 28. The grip portion 26 has an open end portion as in the prior art, and the second shaft portion 5 is inserted into the insertion hole 29 of the tubular portion 27 so that the first shaft portion is rotated around the axis of the second shaft portion 5. When the part 4 is rotated, the first shaft part 4 can be pushed into the grip part 26. Further, similarly to the prior art, the cylindrical portion 27 also has a tapered surface 30 on the distal end side outer surface, and a split groove 31 is formed on the distal end side. As a result, when the tubular portion 27 is inserted into the attachment hole 6 of the handle lever 2 for attachment, the diameter of the tip side is reduced, and the peripheral edge portion of the attachment hole 6 can be easily fitted into the step groove 40 formed at the base of the tubular portion. Can be fitted and mounted.

In the coupling device C having the above-described structure, in the present invention, the step portion 12 engageable with the end surface 27b of the tubular portion 27 is provided on the outer periphery of the second shaft portion 5 projecting from the tubular portion 27 on the distal end side. I am trying to provide it. The step portion 12 is formed by notching the outer periphery of the second shaft portion 5, and by setting the diameter of the second shaft portion 5 to be slightly smaller than the inner diameter of the insertion hole 27c, The step portion 12 does not become an obstacle when the second shaft portion 5 is inserted into the insertion hole 27c.

FIGS. 4 and 5 show another embodiment of the present invention. In this embodiment, a step which can be locked to the inner surface of the insertion hole 27c of the cylindrical portion 27 is provided on the outer periphery of the second shaft portion 5. A part 12 'is provided. This step portion 12 ′ is also formed by cutting out a part of the outer circumference of the second shaft portion 5 like the step portion 12, and when the second shaft portion 5 is inserted into the insertion hole 27 c, the step portion 12 ′ is not formed. There is no obstacle.

FIG. 6 is a front view of a door lock device to which the other end of the link wire 3 is attached. The door lock device B is provided on a vehicle door and includes an open lever 25 pivotally supported by a door lock body 22 through a pin 21 and a latch 23 that is rotated by the operation of the open lever 25. Prepare The open lever 25 is an actuating piece according to the present invention, and like the handle lever 2 in the above-mentioned handle device A, the other end of the link wire 3 is connected via the connecting device C including the locking piece 1 and the fastener 7. The parts are connected. The latch 23 can be engaged with a striker (not shown) provided on the vehicle body side when the vehicle door is closed, and the engagement state with the striker is released when the open lever 25 is opened. It The link wire 3 is slidably inserted into the outer wire 41, and each end portion derived from the base 11 provided at the end portion of the outer wire 41 is connected to the handle lever 2 and the open lever 25, respectively. To be done. Further, each base 11 is fixed to a wire locking portion 30 provided on the handle case 30 and the door lock body 22, respectively. In this way, the handle lever 2 and the open lever 25 are linked to each other via the link wire 3, and the latch 23 and the striker (not shown) are released from the engaged state according to the pulling operation of the handle lever 2. The vehicle door will be opened. In the above-mentioned embodiment, the link wire 3 is used as the linking means, but the connecting device C is similarly applied even if it is a rod.

Next, the operation of this embodiment will be described. Vibrations and shocks generated while the vehicle is running are applied to the locking piece 1 via the link wire 3 or directly. When the vibration or shock is relatively small, the first shaft portion 4 of the locking piece 1 is gripped by the grip portion 26 of the fastener 7, so that the movement of the locking piece 1 due to such vibration or shock is suppressed. (Stopped). When the vibration or the impact is relatively large, the locking piece 1 tries to move against the gripping force of the gripping portion 26. The movement of the locking piece 1 at this time is that the second shaft portion 5 is tilted as indicated by arrow X in the embodiment shown in FIG. 2 because the link wire 3 is connected to the first shaft portion 4. Move away from the cylinder 27. At this time, the step portion 12 provided on the second shaft portion 5 of the locking piece 1 engages with the end surface 27C of the tubular portion 27 of the fastener 7, so that further movement of the locking piece 1 is suppressed, and accordingly, Generation of noise such as chattering noise based on such movement is suppressed. In the embodiment shown in FIG. 4, when the vibration or shock is relatively large, the second shaft portion 5 of the locking piece 1 moves in the direction to separate from the tubular portion 27, and at this time, the second shaft portion 5 is provided. The stepped portion 12 ′ tries to bite and lock the inner surface of the insertion hole 27 C of the cylindrical portion 27, so that the further movement of the locking piece 1 is suppressed, and accordingly, the chattering noise based on such movement is generated. The generation of noise is suppressed.
