The groove 1a for locking the cylindrical cable end 2a of the first cable 2 and the cable end 3a of the second cable 3 are engaged. The stop groove 1b is formed so as to penetrate both engaging pieces 1c, 1c.
The cable ends 2a and 3a are inserted into the lanes 1a and 1b such that their axes coincide with the axes of the through-grooves, and are engaged so as to span the respective grooves.

In general, in a vehicle manufacturing line, the equalizer 1 and the first cable 2 are connected to the groove 1a.
The equalizer 1 and the second cable 3 are supplied to the production line in a state where the cable end 2a is assembled. However, the engagement between the groove 1a and the cable end 2a is disengaged in a connection step of a cable brake lever or the like, and the cable end 2a rotates in a direction along the U-shaped opening as shown in FIGS. There are cases. When the first cable 2 is pulled upward in the drawing in such a state, the cable end 2a gets into the equalizer 1 as shown in FIG. 11, the equalizer 1 is deformed, and the second cable 3 comes off the equalizer 1. was there.

As cable connecting structures which can solve such a problem, there are those disclosed in Japanese Utility Model Laid-Open No. 59-125466 (first conventional example) and Japanese Utility Model Laid-Open No. 1-111064 (second conventional example). The first conventional example has a structure in which an opening for inserting the cable end into the equalizer is provided in one of the opposite locking pieces of the equalizer, and a groove for guiding the cable from the opening to the locking end face of the cable end is formed. Further, the second conventional example has a structure in which the opposite locking pieces of the equalizer are once pushed open to engage the cable end fasteners with the equalizer, and then the two locking pieces are returned to the original shape. It is shown.

[0005]

However, since the first prior art has a structure in which the opening and the groove are provided in the locking piece of the equalizer, there is a problem that the strength of the equalizer is reduced.
Further, since the second conventional example has a structure in which the interval between the locking pieces of the equalizer is enlarged or reduced, there is a problem that the number of processing steps is increased and the assemblability is poor.

The present invention has been made in view of the above-mentioned conventional problems, and can prevent the cable end from dropping out of the locking groove of the equalizer without causing a decrease in strength and a deterioration in assemblability. It is an object of the present invention to provide a parking brake cable connecting structure capable of preventing deformation.

[0007]

According to the present invention, there is provided a parking brake cable connecting structure in which a first cable on a parking brake lever side and a second cable on a brake mechanism side are connected via an equalizer. And an equalizer in which a rod-shaped cable end is integrally connected to an end of the inner cable, and the equalizer is formed in a U-shape in which the second cable side is opened, and two opposite locking pieces of the equalizer are formed. The second cable side is opened to form a locking groove through which the cable end of the first cable is locked, and only the locking piece on one side is provided in the open portion of the locking groove of the locking piece. It is characterized in that a locking portion for preventing movement of the end toward the brake mechanism is formed.

[0008]

According to the parking brake cable connection structure of the present invention, in order to connect the first cable to the equalizer, the cable end of the first cable is hooked over the locking grooves of both locking pieces and locked. . In this case, in the present invention, only one of the locking pieces is provided with a locking portion at the open portion of the locking groove of the locking piece to prevent the cable end from moving to the brake mechanism side. The cable can be easily connected to the equalizer, and the cable end does not move in the cable connection step or the like, and the cable end can be prevented from dropping out of the groove of the equalizer, and thus the strength and the assemblability can be reduced. The deformation of the equalizer can be prevented.
