PURPOSE: A sealing device for a gate is provided to prevent damage to a watertight rubber when a gate is opened and closed using first and second guide plates and a linear guide plate. CONSTITUTION: A sealing device for a gate comprises rollers(100,100'), first and second guide plates, a drive shaft(130), and a driven shaft(140). The rollers are installed on the bottom end of a gate. The first and second guide plates touch the rollers and are composed of curved portions, inclined guide portions, and fixing pieces. The inclined guide portions guide the rollers to fixing portions through the curved portions. The fixing pieces restrict the descent of the rollers. The drive and driven shafts rotate the gate. |
