An impeller and a structure for connecting the impeller to a motor shaft is provided to reduce pressure loss, thereby improving performance of the impeller and increasing durability thereof. An impeller includes a support plate(110), a boss(120), and a vane(130). The support plate is formed of a stainless steel plate to have a circular shape. The support plate is rotated to generate pressure energy. The boss is pressed using a stainless steel plate to be coupled to a center part of the support plate. The boss is connected to a motor shaft(210) to transmit a rotational force of the motor shaft to the support plate. The vane is pressed using a stainless steel plate to be integrally formed with the boss. The vane is formed in plural to be disposed about a center of the boss at predetermined intervals, and rotated to generate vortex and pressure energy.
