To provide a rotor manufacturing device which can easily position a rotor body when supplying resin in a housing hole in a device for manufacturing a rotor including the housing hole for housing a magnet.SOLUTION: A rotor manufacturing device 1 comprises: a rotor body 21 which includes a hole 211 positioned in the center part and a housing hole 212 for housing a magnet 22; and a magnet 22 stored in the housing hole 212. The rotor manufacturing device is for manufacturing a rotor in which the magnet 22 is fixed with resin in the housing hole 212. The rotor manufacturing device 1 comprises: a resin housing space part 31 in which resin to be supplied to the inside of the housing hole 212 is stored; a passage 32 which flows melted resin into the housing hole 212; a first mold 3 which includes a contact part 33 which is inserted to the hole 211 and comes into contact with inner peripheral surface of the hole 211; and a second mold 4 which sandwiches the rotary body 2 between the first mold 3 and itself.SELECTED DRAWING: Figure 1 【課題】磁石を収容する収容孔を有する回転子を製造する装置において、前記収容孔内に樹脂を供給する際に、回転子本体を容易に位置決めできる回転子製造装置を提供する。【解決手段】回転子製造装置１は、中央部に位置する孔２１１と磁石２２を収容する収容孔２１２とを有する回転子本体２１と、収容孔２１２内に収容される磁石２２とを有し、収容孔２１２内で磁石２２が樹脂によって固定される回転子を製造するための回転子製造装置である。この回転子製造装置１は、収容孔２１２内に供給される樹脂が収容される樹脂収容空間部３１と、収容孔２１２内に溶融した樹脂を流す流路３２と、孔２１１内に挿入されて孔２１１の内周面に接触する接触部３３とを有する第一型３と、回転子本体２を第一型３との間で挟み込む第二型４と、を備える。【選択図】図１
