The present invention relates to a grommet expander for enlarging an automobile grommet. The present invention comprises: an operation input unit for receiving an operation input from an operator; a drive force providing unit for providing drive force to the grommet expander in accordance with the input of the operation input unit; and an enlargement unit which receives the drive force to enlarge the grommet in the drive force providing unit. According to the present invention, the drive force provided in the drive force providing unit is cut off, whereby the enlargement unit is freely reduced by restoring force of the grommet. According to the present invention, since the pneumatic pressure is not applied when a chuck is shrunk, an effect of preventing wiring from being damaged is caused.

    본 발명은, 차량용 그로멧을 확대시키는 그로멧 확대기로서, 작업자로부터 동작 입력을 받는 동작 입력부, 상기 동작 입력부의 입력에 따라 상기 그로멧 확대기에 구동력을 제공하는 구동력 제공부 및 상기 구동력 제공부에서 구동력을 제공받아 상기 그로멧을 확대시키는 확대부를 포함하고, 상기 구동력 제공부에서 제공되는 구동력이 차단됨으로써, 상기 확대부가 상기 그로멧의 복원력에 의해 자유롭게 축소되도록 하는 것을 특징으로 한다. 본 발명에 의하면, 척이 축소될 때 공압을 인가하지 않음으로써, 와이어링이 손상되는 것을 방지할 수 있는 효과가 있다.
