Abstract

A CENTRIFUGAL-TYPE MULTIBLADE FAN HAS A PLURALITY OF BLADES DISPOSED AROUND A ROTARY SHAFT, A DISC-LIKE DRIVE PLATE CONNECTED TO ALL THE BLADES AT FIRST ENDS OF THE BLADES, AND AN ANNULAR CONNECTION RING CONNECTED TO ALL THE BLADES AT SECOND ENDS OF THE BLADES POSITIONED OPPOSITE TO THE FIRST ENDS, AND IN THE MULTIBLADE FAN, A GUSSET IS PROVIDED TO A CONNECTION PORTION CONNECTING A POSITIVE-PRESSURE SURFACE OF EACH BLADE AND A RADIALLY OUTER EDGE OF THE DRIVE PLATE. PROVIDED IS AN IMPROVED MULTIBLADE FAN WHICH CAN PREVENT OCCURRENCE OF A CRACK AND THE LIKE AT THE CONNECTION PORTION CONNECTING EACH BLADE AND THE DRIVE PLATE, THEREBY INCREASING THE DURABILITY OF THE FAN.
