PURPOSE:To easily clean the inside of a sleeve by providing a coupling part to be coupled with an optical connector adaptor inserting an optical connector ferrule into the front part of a body case with a knock for operating a collet chuck on the rear part of the body case. CONSTITUTION:Since a supporting rod 2 fitting a cleaning member 1 to its tip is held by a collet chuck 3 and clamped by a spring 8 fitted between a spring stopper 8 and the knock 9, the supporting rod 2 fitting the cleaning member 1 can be attached/detached by pressing the knock and loosening the clamping force of the spring 8. The cleaning member 1 is formed by an elastic material and its outer diameter is slightly larger than the inner diameter of the sleeve 21. Thereby, the cleaning member 1 is pressed by the spring 5 in the axial direction at the time of being inserted into the sleeve 21, stuck to the coupling end face of the ferrule 22 and contacted with the inner periphery of the sleeve 21 with elasticity. When the knock is rotated under said status, the cleaning member 1 is rotated in the sleeve 21 and the inner periphery of the sleeve 21 can be also cleaned in addition to the coupling end face of the ferrule 22.
