Abstract:
1. A shower device comprising: a driving unit including a housing, which has space inside, and water being introduced inside the housing; and a core, which divides the space inside the housing into a first pressure chamber and a second pressure chamber, and reciprocates relative to the housing, the core reciprocating by a pressure of the water which is introduced into the housing; a shower part allowed to swing; a water guide channel introducing water which is introduced into the housing to the shower part; and a power transmission part transmitting the reciprocating motion of the core to the shower part, the core having a core inner channel communicating with the first and second pressure chambers via a valve body which reciprocates relative to the core, the water in the first and second pressure chambers being introduced into the core inner channel from drain holes in the core, wherein openings of the drain holes change with the valve body movement, and the core inner channel communicates with the water guide channel, the water introduced into the housing acting as a thrust of the reciprocating motion of the core and the water being sprinkled from the shower part via the core inner channel and the water guide channel.
