A disc brake including: a piston; a cylinder including a bore portion, which movably accommodates the piston, and a step portion formed on an opening end side of the bore portion; and a piston boot arranged between a tip side of the piston and a small diameter step portion of the cylinder. The piston boot includes: a large diameter annular fitting portion containing an annular metal member so as to be fitted to the small diameter step portion; a bellows portion, which extends from the large diameter fitting portion, is increased in its diameter from the large diameter fitting portion to an outer peripheral side, and is also deformed and extended from the large diameter fitting portion toward an inner peripheral side; and a small diameter fitting portion formed at an end portion of the bellows portion so as to fit to an outer periphery of the piston.

[Problem] To provide an optical cable connecting closure and optical interconnection system which can easily respond to changes in required connection functions if any. [Solving Means] An optical cable connecting closurehas a case, while a plurality of connecting modulesare arranged (stored) so as to be erected with respect to the bottom face of a closure main bodyalong the width direction in a module storing sectionof the case. The connecting modulehas a rectangular parallelepiped board-like module main body, while a plurality of MT connectorsare attached in a vertical row to one end face of the module main body. In the module main body, an optical connecting sectionfor connecting the MT connectorsto each other is arranged. The module storing sectioncan store a different kind of connecting module having a connecting configuration (function) different from that of the connecting module
