DRIVE UNIT AND VALVE DEVICE
Document Type and Number:
Japanese Patent JP2020153512
Kind Code:
A
Abstract:
To provide a drive unit which is constituted so as to hardly receive influences of the processing accuracy and the assembling accuracy of a component related to the withdrawal of an output of a reduction mechanism, and has a structure which can stabilize a rotation force outputted from the reduction mechanism, and can improve quietness, and a valve device.SOLUTION: A reduction mechanism 43 comprises an outside annular gear 62 and an inside rolling gear 63 which is arranged inside the outside annular gear 62, and rotates accompanied by a revolution generated by the drive of an electric motor 42 in a state of being engaged with the outside annular gear 62. An output part of the reduction mechanism 43 comprises an output-side rotating body 65 which is rotatably supported around a reference axial core L1 being a revolution axial core of the inside rolling gear 63, and connected to the inside rolling gear 63 in a non-contact state by a magnetic force.SELECTED DRAWING: Figure 3
