A steering wheel remote controller for a car is provided to enable a driver to select operational functions more conveniently when controlling degrees of sound volume or selecting one among several functions. A steering wheel remote controller for a car comprises a housing(10), a scroll button(20), an encoder(30), a switch(40), a first supporter(11), and a second supporter(12). The housing is mounted to a steering wheel of the car. The scroll button is mounted to the housing and rotated in a scrolling manner. The encoder is connected to one end of the scroll button, and outputs a code signal according to the rotation of the scroll button. The switch is disposed on the other end of the scroll button and is switched on as the other end is pressed. The first supporter is formed on the housing and has a supporting groove(11a) at one end to support both sides of a shaft of the scroll button. The second supporter is distanced from the first supporter and has a guide groove(12a) enabling the shaft to press the switch.
