Abstract
A disk brake capable of improving fabrication efficiency and having a transmission member. The transmission member () includes: an anti-rotation locking portion () formed on an outer circumferential portion of the transmission member, the anti-rotation locking portion being slidably fitted into a fitting area () on a cylinder () side so as to restrict rotation relative to the cylinder; and a seal groove () formed in an inserted portion (). The seal groove stores a sealing member () for defining an internal space in the cylinder () and a cam chamber (). The anti-rotation locking portion is fitted into the fitting area () on the cylinder side before the sealing member is positioned inside a hole () when the inserted portion () of the transmission member () is inserted into the hole.
