Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an expansible hose that can set up the operation power for extension at the discretion and comparatively lighter operation force than the conventional one and handle easily, in the flexible hose that is mainly used for a cleaner hose. SOLUTION: A part of helical spring (2) among helical springs (2) (3) arranged in plural stripes is made in a compression spring and another part (3) is made in an extension spring. And the hose (1) with light operation force of extension direction is obtained by maintaining the contraction of a hose body (10), in a compressed condition where the helical spring (3) consisting of the above compression spring is compressed against its spring force by the return force of the helical spring (2) consisting of an extension spring.
