The invention discloses a kind of swing type endoscope apparatus that wire body is no-welding, and it includes oscillating head mechanism, deflection division, support portion, wire body and two-way flexible bodies. Oscillating head mechanism has introscope head group, the first guidance part and the second guidance part. Deflection division connects what oscillating head mechanism, and deflection division has the first accommodating space. Support portion connects deflection division, has the second accommodating space in support portion. In two-way flexible the first accommodating space of position what, the fixed what oscillating head mechanism in two-way flexible body one end, the fixed what support portion of the other end. Wire body passes through the first guidance part via the second accommodating space, the first accommodating space, when wire body passes through the first guidance part Hou, wire body bypasses the side wall of oscillating head mechanism, and is crossing to the second guidance part, when wire body passes through the second guidance part Hou, wire body is crossing to the second accommodating space via the first accommodating space.本發明揭露一種線體免焊接之擺動式內視鏡裝置，其包含擺頭機構、撓曲部、支撐部、線體及雙向可撓體。擺頭機構具有內視鏡頭組、第一導引部及第二導引部。撓曲部連接於擺頭機構，撓曲部具有第一容置空間。支撐部連接撓曲部，支撐部內具有第二容置空間。雙向可撓體位於第一容置空間中，雙向可撓體一端固定於擺頭機構，另一端固定於支撐部。線體經由第二容置空間、第一容置空間而穿越第一導引部，當線體穿越第一導引部後，線體繞過擺頭機構之側壁，而穿越至第二導引部，當線體穿越第二導引部後，線體經由第一容置空間而穿越至第二容置空間。
