After landing on Runway 6; the plane rolled for about 50 yards then abruptly veered 45 degrees to the left and settled on the grass. The plane was not damaged. There were no injuries and there was no damage to airport equipment. I was able to taxi to parking and inspected each wheel and could find no apparent cause. I then looked at the parking brake handle and noticed that it was slightly pulled out.
C177 pilot reported a loss of control and runway excursion during landing rollout.
