To provide a two-leading type drum brake that reduces a difference in a braking force for braking the rotation of a rotating drum in forward and backward running.

A brake shoe 20 includes a first link 58 having an outer circumferential end 58b turnably coupled to one end of the brake shoe 20, and an inner circumferential end 58a turnably coupled to a tip 54a of a fixed link (first fixed member) 54, the inner circumferential end 58a being separated in a circumferential direction further from a first wheel cylinder 22 than the outer circumferential end 58b. When one end of the brake shoe 18 is moved to the outer circumference of a backing plate 16 by the first wheel cylinder 22, the first link 58 is rotated so that the inner circumferential end 58a comes close to the first wheel cylinder 22 in the circumferential direction via the fixed link 54, thereby separating the one end of the brake shoe 20 from the other end of the brake shoe 18 by the first link 58.
