The object of this invention is to provide a portable device for polishing cars. In the device, a drive motor (16) having a worm (17) is set in a housing (10), and is operated by electricity supplied from the lighter jack of a car through an electric cord (15). A crankshaft (20) and a corotating shaft (30) are each rotatably held in the housing (10), and each have a crank pin part (22, 32), which is eccentric from the shaft's central axis by 2mm. The crankshaft (20) has a worm gear (26) engaging with the worm (17). A vibrating shaft (40) is coupled to the crank pin parts (22, 32) using bearings (41, 42) provided at both ends thereof. A cloth housing (50) is mounted to the vibrating shaft (40), with a cloth (70) set in the cloth housing and biased downward by a tension unit (52). |
