On one portion of the front surface (210) which is at least 70% of the diametrical range that defines the blade installation area (22), the front surface (210) is tangential to a cone, the tip of which is pointed forward and the vertex angle of which is between 154° and 170°. The invention also relates to a rotating machine and a turbocompressor comprising such a wheel.
