     상기 실린더튜브(100) 및 실린더로드(200)의 결합부를 결합수단으로 각각 결합시키는 것에 있어서; 
     상기 상부로드(210)와 하부로드(220)의 결합부는 상부튜브(110)와 하부튜브(120)의 결합부 위치보다 소정의 거리()만큼 상부에 위치시키고, 상부로드(210)의 하단저면에는 볼트부(211)가 하부로드(220)의 상단측에는 이 볼트부(211)에 나사 체결되는 너트부(221)가 각각 구비되며, 상부튜브(110)의 하단부에는 링상의 상부조립홈(131)가 형성되고, 하부튜브(120)의 상단부에는 링상의 하부조립홈(132)가 파여져, 이 상,하부조립홈(131)(132)가 대응하는 단면으로 한쌍의 조립밴드(130)(140)가 볼트(150) 및 너트(151)로 체결됨과 아울러 이 조립밴드(130)(140)에는 그 조립위치를 결정하기 위한 위치결정핀(152) 및 이를 수용하는 위치결정홈(153)과 한쌍의 영구자석(154)(155)이 그 대응되는 위치에 설치되는 것에 의해, 실린더튜브의 조립을 조립밴드에 의해 조립하도록되어 있어 구조적으로 안정되면서 조립이 용이하고 실린더로드 또한 볼트와 너트부를 가공하여 조립하도록하므로 안정된결합구조를 하면서 조립작업이 단순하고 하부로드(220)가 하부튜브(120)보다 길게 설계되므로서 별도의 준비작업 없이 실린더를 간단하고 신속 용이하게 조립가능하다. 
     또한, 현장작업시에도 분리 및 조립이 용이하여 운반이 용이할 뿐만아니라 별도의 설치보조기구나 보조 작업자 없이도 누구나 분해 조립이 가능하여 제품의 신뢰성 및 상품성이 향상되는 등의 매우 유용한 발명인 것이다.
