The inner cable 13 is subject to severe wear due to sliding friction with Jb, and as a result, the inner cable 13 may break.The metal guide part l is easily rusted, which is unfavorable from a safety standpoint. There was a problem in that rubbing noise was likely to occur between the inner cable 13 and the guide section /jl).

The cylindrical end 1.21 of the cable guide member 12 is fixed to
The semi-cylindrical guide part l of this guide member / is extended toward the end of the parking lever, and its tip / Jc f is inserted into the back plate l.
The semi-cylindrical guide member 44 is made of a wear-resistant soft material such as synthetic resin or rubber and is fixed to the semi-cylindrical guide member 44 and has a substantially M-shaped cross section as shown in FIG. /Jb and connect the inner cable 13 connected to the end of the parking lever 6 to the concave groove of the guide member 74C /US
Ask K to guide you. Note that these are claws that protrude inward from both leg ends of the tub a guide member ip. 4 and 7 show another embodiment, in which the aforementioned guide member 1 is eliminated and a soft guide member is directly fixed to the back plate 1. In other words, the holder i fixed to the cap fitting /l provided at the end of the outer cable 10 of the parking brake cable to the back plate)/
A soft guide member 16 is press-fitted into the block s and is made of a soft material having abrasion resistance such as synthetic resin or rubber and has a protrusion/Am protruding from the bottom surface of a block having a substantially concave cross section as shown in FIG.
The guide member 16 is fixed to the back plate I by inserting the protrusion 14m of the guide member/B into the hole/a provided in the back plate/, and guides the inner cable 13 connected to the sixth end of the parking lever. Groove 16 of member 16

When the parking brake lever is operated, the operating force is transmitted to the inner cable /J of the parking brake cable, and the inner cable /J slides against the guide member 1 or the concave groove 1lati of 16 against /4b, and then the parking lever 4 By pulling , the brake shoe (not shown) is expanded and the brake is applied.

。Also, when the parking brake is released, the inner cable 13 becomes loose and by returning the parking lever 6, the brake shoe is pulled back by the return spring.

が容易になるという効果が得られる。As a result, the parking brake is released.In other words, when the parking brake is operated, the inner cable 13 always slides against the guide members #, /4, but in this invention, the inner cable 13 slides against the guide members /4c, /4. Since it is made of a soft material with abrasion resistance such as synthetic resin or rubber, there is no risk of the inner cable 13 being worn out and broken unlike in devices with conventional metal guide members, and there is no risk of cracking or rubbing noise. As explained above, according to the present invention, the wear and rust of the inner cable and the scraping sound during sliding can be prevented, and the durability of the parking brake device can be improved. Since the resistance of the sliding part can be reduced compared to the metal contact, the load loss is also small and the braking operation becomes easier.
