Claim 4:
5. A rotating machine according to claim 1, wherein comprising: a stator and a rotor;
an outer frame member that covers the stator and the rotor from an outer side in a radial direction over an entire circumference in a circumferential direction;
a cover member that has a surface on one side in an axial direction and covers an other side in the axial direction of the outer frame member;
a blower blade that rotates in accordance with rotation of the rotor; and
a wind guide member that guides wind taken in from a ventilation inlet by rotation of the blower blade to a ventilation outlet, wherein
the ventilation inlet is a through hole that penetrates the cover member in the axial direction,
the ventilation outlet is a through hole that penetrates the cover member in the axial direction,
the wind guide member expands from the surface on one side in the axial direction of the cover member toward the blower blade between the ventilation inlet and the ventilation outlet, and
a position in the radial direction of the end portion on the one side in the axial direction of the wind guide member is located at a position where a ratio of a distance in the radial direction from an end portion on an inner side in the radial direction of the blower blade to a distance in the radial direction between an end portion on an outer side in the radial direction and the end portion on the inner side in the radial direction of the blower blade falls within 55% to 65%.
