The trampoline having an electric lifter and a pneumatic mechanism, comprises a pneumatic mechanism (2) with a cylinder for supporting vertical vibration of a pedal, a piston reciprocating in the cylinder, a rod projected from the upper header and fixed at the piston; a rotating means (3) for the pedal (1); upper/lower guide means (4) for the pedal (1); a lifting means (5) for the pedal; an upper point damping means (7) and a lower point damping means (8) for the respective pneumatic mechanisms (1)(2). The rotating means (3) comprises a support plate (31) fixed at the upper rod (25); bearing elements at the center of the pedal (2); a fixing pin mechanism (35) inserted to the groove (34) of the pedal; a fixing pin manipulating mechanism (38) for manipulating the mechanism (35).
