<p>The present invention provides a dispensing device by which power transmitting efficiency can be promoted and a decrease in the electric field of the overall device can be promoted. An output shaft (32) having a screw groove on the outer circumferential surface is rotated based on a shaft core of an output shaft (32) by means of the operation of a rotary actuator (31), so that a piston (33) which is screwed in the screw groove of the output shaft (32) is roundly moved along the axial direction of the output shaft (32), wherein a liquid is fed and discharged through a nozzle (23) in the front end thereof. An actuator case (35) which is disposed to have a shape that covers the outer circumferential part of a decelerator (312) constituting the rotary actuator (31) is equipped, wherein he actuator case (35) supports an output end unit (322) to be able to be rotated by interposing a bearing member (37) in the front end part thereof so as to couple the output end unit (322) of the output shaft (32) with a drive shaft unit (323c) of the decelerator to be able to be operated and transferred.</p> |
