矩形管体の小管体の外側面に凹凸を有する合成樹
脂被覆面を設けると共に、大管体の端部挿通口に
、該被覆面に対応する凹凸部を有する抵抗部材を
前記被覆面に対して接触、離間自在に取付けたこ
とを特徴とする管の伸縮装置。 A synthetic resin coating surface with unevenness is provided on the outer surface of the small tube body of two rectangular tube bodies that allow the small tube body to be inserted into the large tube body with almost no gap, and the insertion opening at the end of the large tube body corresponds to the coating surface. A tube expansion/contraction device characterized in that a resistance member having an uneven portion is attached to the covering surface so as to be able to come into contact with and separate from the covering surface.
