Abstract
A backpack type power working machine includes a movable stopper for restricting the turning angle of an internal combustion engine unit which is supported on a backpack frame so that it turns about a longitudinal axis. As a result, the turning angle restriction of the internal combustion engine unit can be released by just moving the movable stopper, whereby a job efficiency can be improved.
