Claims

[Scope of Claim for Utility Model Registration] In a drum brake strut whose length can be adjusted by bridging the respective brake shoes mounted on the back plate so as to face each other, there is a threaded portion 1 approximately at the center of the inner surface. A cylindrical body 2 having a smooth inner surface on both ends thereof, one end 3a is engaged with one brake shoe, and the other end 3b is fitted in sliding contact with the inner surface on the one end 2a side of the cylindrical body 2. , a first strut member 3 that is integral with the cylinder 2 only in the circumferential direction of the cylinder 2 and further has a pressure receiving part 4 at the tip;
A second strut member 5 whose one end 5a is engaged with the other brake shoe and whose other end 5b has a fitting hole 5c.
It is located between the second strut member 5 and the cylindrical body 2, and has a protrusion 6b at one end 6a that rotatably fits into the fitting hole 5c, and a rotating rod 6d at the other end 6c. The rotor 6 has a disc shape and the cylinder body 2 is screwed into the threaded part 1 in the cylinder body 2.
It has a recess 7b at one end 7a into which the rotating rod 6d fits, and an interlocking element 7 on the other end surface 7c of which the tip of the pressure receiving part 4 comes into contact, so that the rotational force of the rotor 6 is transmitted to the rotating rod. 6d, and the first strut member 3 can be pressed by the interlocking element 7.
