If the chair was chased, the phrase would be `{}{}{}` passively or `{}{}{}` actively.
Back to the question, this `` particle means `from`. I guess you have no problem with `{}{}` (move away from Tokyo). Another grammatically correct phrase is `{}{}{}` (move away from the seat).
Actually, you can say `{}{}` for being chased away from Tokyo. Analogously, you can say `{}{}{}`. For me, the best way to understand the phrase in question is, seeing `{}` as a substitute for `{}` or `{}` (leave).
