The invention provides an underwater propelling device based on opposite long fin fluctuation. A plurality of linear guide rail slide troughs are mounted on two sides of a body of an underwater vehicle, wherein the numbers of the linear guide rail slide troughs at the two sides are equal. The linear guide rail slide troughs are arranged in parallel and are arranged vertically to axial line of the body of the underwater vehicle. Each linear guide rail slide trough is provided with a fin bar, wherein one end of the fin bar is installed on the linear guide rail slide trough through a sleeve. The fins are arranged in parallel with each other and can be moved along the linear guide rail slide trough in a reciprocating manner. A flexible film is tensioned between each two adjacent fin bars. The sleeves at the two sides are all connected to a crank shaft through a connection rod. The crank shaft rotationally moves to drive the connection rod to move along the linear guide rail slide troughs in a reciprocating manner, and further drives the flexible films to fluctuate in a sine manner. The device can be moved flexibly, wherein 180-degree rudder-free steering can be achieved in a small range. The device also can solve the problem of moving back of the underwater vehicle, wherein generated noise is not higher than a background noise. The device is high in movement stability.
