The rear end of the handle connecting member is joined through a vibration isolator to the rear end of the rear handle, and the front upper end of the rear handle is joined through vibration isolator to the top of the engine unit. The upper end of the front handle is positioned in parallel with the upper end of the rear handle in the horizontal direction and joined thereto through a vibration isolator, and the lower end of the front handle is joined directly to the front end of the handle connecting member.
