Abstract
A curved tube for an endoscope includes: a curved tube body including a locked portion provided on an inner peripheral surface of the curved tube body; an operation wire configured to perform a bending operation of the curved tube body; a pipe member which is press-fitted to the operation wire and is locked to the locked portion of the curved tube body; and particles interposed between an outer peripheral surface of the operation wire and an inner peripheral surface of the pipe member. The particles are higher in hardness than materials forming the operation wire and the pipe member and are buried to dig into the outer peripheral surface of the operation wire and the inner peripheral surface of the pipe member.
