Claims

[Scope of utility model registration request]

(1) A case body housing a stator and a rotor, a case end plate attached to an opening at one end of the body, and a fan attached to a rotor shaft passing through a bearing support provided on the end plate; a fan cover that covers the fan and is attached to an opening at one end of the case body; In an electric blower in which the end plate is formed in a shape that crosses in the radial direction and is arranged between the stator windings of the stator with both ends thereof fixed to the opening edge of one end of the case body, the outer shape A first air passage and a second air passage are respectively formed between the stator core of the stator having a substantially rectangular shape and a substantially cylindrical portion of the case body, and the first air passage does not face the case end plate. An electric blower characterized in that the air passage is larger than the second air passage facing the case end plate, and an exhaust hole is provided in the case body on the downstream side in the extending direction of the first air passage.

(2) The electric blower according to claim 1, wherein the exhaust hole is provided closer to the rotational direction of the first air path.
