Abstract
To obtain a hand-held powered suction device, which secures a high suction performance by a lightweight fan while preventing a blade of the fan from being damaged or being broken due to a sucked object. Forming an air intake opening along a driving axis of a fan in a portable-type fan case and providing a fan protection member to be rotated at an upstream side in an air intake direction of the fan within the intake opening being attached so as to be integrally rotated with the driving axis, a shock absorbing surface that is perpendicular in an air intake direction of the intake opening is formed on the fan protection member.
