Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a locking structure for locking the extending end of a cable extending from a clutch to a clutch pedal in an automobile.

(Prior Art) In an automobile, a clutch is usually connected to a clutch pedal by a cable, and the clutch is connected or disconnected by pressing the clutch pedal.

In the above configuration, there is a conventional structure for latching the cable to the clutch pedal as disclosed in, for example, Japanese Utility Model Application Publication No. 151728/1983. According to this, the cable extending from the clutch is pulled by a biasing force toward the clutch.
On the other hand, a hook portion is formed at the upper rotational end of the clutch pedal, and a hook portion is formed at the extending end of the cable, which can be freely hooked and removed from the hook portion.

The to-be-latched object has a fitting hole that fits into the hook portion and has an annular shape in a plan view, and the to-be-latched object is latched to the hook portion by fitting outwardly thereto. In this case, the fitting hole of the hook is shaped to approximately match the cross-sectional shape of each part of the hook to prevent the hook from accidentally coming off the hook.

In the above configuration, the procedure for hooking the object to be hooked to the hook portion will be explained with reference to FIG. 4.

In the figure, 31 is a cable, and this cable 31 is pulled by a biasing force C toward the clutch side. Further, 32 is a clutch pedal, and a hook portion 33 is formed at the upper rotational end of the clutch pedal 32, and a hook portion 33 is formed on the upper rotation end of the clutch pedal 32, and
A hooked body 34 is attached to the second side end and is detachable from the hook portion 33.

When the cable 31 is to be hooked to the hook portion 33, first, the object to be hooked 34 is drawn toward the hook portion 33 against the biasing force C, and then,
The fitting hole 35 of the latched body 34 is fitted into the protruding end 36 of the hook portion 33.

At this time, since the fitting hole 35 of the hooked body 34 almost matches the cross-sectional shape of each part of the hook part 33 as described above, the fitting hole 35 of the hook part 34 is
It is necessary to raise the latched body 34 while bending the cable 31 with the fingers 37 until the axis of the hook 33 substantially coincides with the protruding direction of the protruding end 36 of the hook portion 33.

Then, when the fitting hole 35 is fitted into the protruding end 36 of the hook part 33 as described above, the latched body 34 conforms to the shape of the hook part 33 in a side view as shown by arrow D in the figure. move it in the direction you want. In this case, as described above, each cross section of the hook portion 33 and the fitting hole 35 have shapes that almost match, so that distortion may occur between the hook portion 33 and the fitting hole 35 that are fitted together. It is necessary to fit the object 34 into the hook portion 33 while gradually changing its posture to avoid the problem. Then, when the hooked body 34 is fitted to the state shown by the solid line in the figure and the external force is released, the hooked body 34 is hooked to the hook portion 33, and the work of hooking the cable 31 is completed. Thereafter, this locked state is maintained by the biasing force C mentioned above.

(Problem to be solved by the invention) By the way, the urging force C on the cable 31
is somewhat large, so the hook portion 33
During the work of hanging the cable 31 on the body, while bending the cable 31 with the fingers 37 while resisting this biasing force C, the body 34 to be latched is made to stand up,
Further, it is not easy to fit the hooked member 34 into the hook portion 33 while changing its posture so that it matches the shape of the hook portion 33. In other words, the task of hooking the cable 31 is extremely complicated.

(Purpose of the invention) This invention was made with attention to the above-mentioned circumstances, and the purpose of this invention is to facilitate the work of latching a cable to a hook portion.

(Structure of the invention) The feature of this invention for achieving the above object is that a convex part that projects upward is formed at the projecting end of the hook part.

(effect) The effects of the above configuration are as follows.

When hooking the inner cable (cable) 16 to the hook portion 9 formed at the upper end of the clutch pedal 5, first, the inner cable (cable) 1

Reference numeral 5 designates a clutch pedal, and the clutch pedal 5 is pivotally supported by a pivot shaft 8 to be rotatable back and forth with respect to a bracket plate 7 protruding from the surface of the vehicle compartment 2 side of the dashboard panel 1. A hook portion 9 is formed at the upper rotational end of. Further, the lower rotating end of the clutch pedal 5 is a treading portion 12, and the clutch pedal 5 is supported by a spring so that the hook portion 9 rotates forward and the treading portion 12 rotates backward. (not shown) urging force A
is energized by Further, at this time, a screw-type stopper 13 that comes into contact with the clutch pedal 5 is provided so that the treading portion 12 does not rotate further backward.

A clutch cable 14 is interposed between the clutch 4 and the clutch pedal 5. This clutch cable 14 is composed of a tube-shaped outer cable 15 and an inner cable 16 that is slidably fitted into the outer cable 15. One end of this inner cable 16 is connected to the clutch 4, and this inner cable 1
