DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to a steering wheel side circuit and the vehicle body side circuit of the vehicle to position the retaining structure of the cable reel is electrically connected.

[0002]

2. Description of the Related Art Conventionally, a cable reel wound with a spiral wire has been used to electrically connect a circuit on a steering handle and a circuit on a vehicle body of a vehicle. The spiral wire of the cable reel is gently wound so that the right and left rotations can be freely rotated by a predetermined number of rotations from a neutral position so as not to hinder the rotation operation of the steering handle. However, if the cable reel is connected to the steering handle with the neutral position set incorrectly, the spiral wire will reach the winding limit while rotating the steering handle to the left or right, and the rotation of the steering handle will be hindered. Has occurred.

In order to prevent such a problem, a technique disclosed in, for example, Japanese Utility Model Laid-Open No. 2-103848 has been proposed. That is, in the prior art,
A rotating gear was provided on the outer peripheral surface of the cylindrical body of the movable case, a fixed gear was provided inside the fixed case, a planetary gear was interposed between the rotating gear and the fixed gear, and a neutral position was detected by the position of the planetary gear. .

[0004]

However, in the case of the technique disclosed in Japanese Utility Model Laid-Open Publication No. 2-103848, since the position of the planetary gear continuously changes with the rotation of the movable case, the neutral position and the neutral position are not changed. The boundary with other positions is unclear, causing a setting error of the neutral position. In addition, even if the setting of the neutral position is successful before connecting the steering handle, there is a problem that an error in the neutral position occurs when the steering handle is connected.

[0005]

SUMMARY OF THE INVENTION The present invention was inventions in view of the problems above mentioned. The present invention aims to hold the cable reel in a neutral position until the steering handle is connected to the cable reel, or to hold the cable reel in that position even when the steering handle for vehicle maintenance is removed. Means are provided. That is, the cancel cam is steered to the cylinder.
Coil spring biasing in the direction of the steering handle , and
A turn signal switch body inserted and attached to said cancel cam, a cable reel which is inserted into the turn signal switch body as well as accommodating the spiral wires respectively connected to the other end to the steering wheel side circuit to the vehicle body side circuit at one end, a in the configuration wherein the cancel cam, and a recess <br/> formed in the axial direction of the cancel cam, and an engaging portion engaged in a groove formed in the cable reel, which has a, the turn A signal switch main body is adjacent to the cylindrical portion , and a shaft is
Has a holding portion with a claw that protrudes toward the center side, and when connecting the front <br/> Symbol steering handle cable reel
The steering handle is the coil spring
With lowering the cancel cam against disengages from the pawl and the recess claws of the holding section was fitted
Providing position holding structure of the cable reel, characterized in Rukoto.

1 to 4 show a preferred embodiment according to the present invention. In FIG. 1, reference numeral 1 denotes a turn signal switch main body in which a coil spring 2 and a cancel cam 3 are inserted into a cylindrical portion 11, and 4 denotes a spiral wire having one end connected to a steering handle 5 side circuit and the other end connected to a vehicle body side circuit. 41 is a cable reel wound around the turn signal switch main body 1 while being wound. The cancel cam 3 is moved in the axial direction of the cancel cam 3 (arrow B).
Respectively in a direction), and the concave portion 31 and convex portion 32, an engagement portion 33 engaged with the groove 42 of the cable reel 4,
And the projections 34 and 35 that fit into the fitting holes 51 and 52 of the steering handle 5, and the cancel pin 36. Further, the turn signal switch main body 1 has a holding portion 12 adjacent to the cylindrical portion 11. As shown in FIG.
A claw 12a projecting toward the axial center of the
ing. Further, the cable reel 4 has a projection 43 that fits into the fitting hole 53 of the steering handle 5.

[0007] Here, the holding unit 12 will be described together with operation of the relationship between the two for the recesses 31 and <br/> protrusion 32. First, as shown in FIG. 3, the holding portion 12 is located at a target position around the cancel cam 3 mounted on the cylindrical portion 11 for a total of two.
The cross section has an inverted L-shape as shown in FIG. On the other hand, the concave portion 31 and the convex portion 32 are provided at, for example, 12 places at the end of the cancel cam 3, respectively.
When the steering handle 5 is not connected to the cable reel 4 as shown in FIG.
Is pushed in the axial direction of arrow B by the coil spring 2, the holding portion 12 is fitted into the concave portion 31, and the cancel cam 3 is fixed. At this time, the cancel cam 3 is engaged with the cable reel 4 via the engaging portion 33, and as a result, the rotation position of the cable reel 4 is held by fixing the cancel cam 3 by the holding portion 12 as described above. Will be done.

Accordingly, the cable reel 4 is set to the neutral position in the production process of the turn signal switch body 1 and the cable reel 4, the holding portion 12 if fitted in the recess 31, the assembly process for the vehicle The cable reel 4 is held at the neutral position until the steering handle 5 is connected to the cable reel 4. Further, when the steering handle 5 is detached from the cable reel 4 during vehicle maintenance, the concave portion 31 having the plurality of holding portions 12 is provided.
And the cable reel 4 is held at the rotation position when the steering handle 5 is removed. Therefore, vehicle maintenance is completed and the cable reel 4
It is not necessary to reset the cable reel 4 to the neutral position each time the steering handle 5 is connected again.

[0009] Next, when the steering wheel 5 as shown in FIG. 2 connected to the cable reel 4 from the state shown in FIG. 1, the cancel cam 3 is pushed in the axial direction of the arrow C by the steering wheel 5. Thereby, the holding unit 1
The engagement relationship between the recess 2 and the concave portion 31 of the cancel cam 3 is released, and the cancel cam 3 and the cable reel 4 can freely rotate with the steering of the steering handle 5. If it is desired to hold the cancel cam 3 only at the neutral position, about one or two concave portions 31 may be provided. Further, the engagement portion 33 of the cancel cam 3 may be disengaged from the groove 42 of the cable reel 4 when the holding state by the holding portion 12 is released.

[0010]

The present invention has the following effects due to the above-described configuration and operation. That is, the present invention is cancel cam includes a recess <br/> formed in the axial direction of the cancel cam, and an engaging portion engaged in a groove formed in the cable reel, which has a, the turn A signal switch main body is adjacent to the cylindrical portion , and a shaft is

The steering handle is the coil spring
With lowering the cancel cam against disengages from the pawl and the recess claws of the holding section was fitted
By holding the cable reel in the neutral position until the steering handle is connected to the cable reel,
Even when the steering handle is removed for maintenance of the vehicle, the cable reel can be held at the position at that time, and the workability of the worker during the assembly work on the vehicle and the maintenance of the vehicle is improved.
