PROPELLER FAN FOR ELECTRIC FAN, ELECTRIC FAN WITH PROPELLER FAN, AND MOLDING DIE FOR PROPELLER FAN FOR ELECTRIC FAN

摘要

PROBLEM TO BE SOLVED: To provide a propeller fan capable of feeding out comfortable wind showing a low pressure variation of generated wind and capable of reducing noise.SOLUTION: A propeller fan 10A comprises a rotating shaft part 11 and a blade 12A including a front edge part 13, a rear edge part 14, and an outer edge part 15. The outer edge part 15 has a forward outer edge part 17b positioned at the front edge part 13, a rear outer edge part 14c positioned at the rear edge part 14, and a connecting part 17a for connecting these front outer edge part 17b and rear outer edge part 17c. Under a state in which the blade 12A is seen as a top plan view along a central axis 20, a maximum radius R1of the outer edge part 15 of a portion corresponding to a first bulged-out part 17b and a maximum radius R2of the outer edge part 15 of a portion corresponding to a second bulged-out part 17c satisfy a condition of R1R2.SELECTED DRAWING: Figure 7
