。In a slack adjuster cam support mechanism for a drum brake that adjusts clearance by rotating a slack adjuster cam pivotally supported on a brake base, the head is provided with a connecting portion 10 formed by chamfering a circular bar-shaped side surface. End 1
A slack adjuster cam 6 is inserted into the screw adjuster cam 1 and fixed in a caulked manner, and is connected to the head end 11 to connect the large diameter portion 12 to the large diameter portion 12.
A camshaft 9 is provided with a small diameter portion 13 connected to the camshaft 9, and a brake base 7 is provided with a camshaft 9 which is opened inwardly, and whose bottom internal diameter is the same as the diameter of the large diameter portion 12 of the camshaft 9. Inner guide groove 2 formed in a truncated conical shape whose diameter gradually increases toward the opening edge
0, and provided in the partition wall 15 in connection with the inner guide groove 20,
An insertion hole 21 formed to have a diameter that is spaced from the small diameter portion 13 of the camshaft 9, one seat surface is brought into contact with the outer surface of the partition wall 15, and the other seat surface locking band 23 is connected to the spring receiver 22. A coil spring is fitted with an initial compressive force so that the slack adjuster cam 6 bends when receiving the contact force of the maximum allowable value of the coupling portion 10. 18. A support mechanism for a slack adjuster cam in a drum brake, characterized in that a support mechanism for a slack adjuster cam is provided.
