PROBLEM TO BE SOLVED: To provide a rotary pump device wherein the rotary shaft of a rotary pump and the drive shaft of a motor are separably and integrally intercoupled in series through a coupling and the rotary shaft and the drive shaft intercoupled in series are rotatably supported in three points through a bearing. SOLUTION: The rotary shaft 18 of a rotary pump and the drive shaft 28 of a motor are separably and integrally intercoupled through a coupling 30 with their axes coinciding with each other. The two ends of the rotary shaft 18 are rotatably supported at the casing 16 of the rotary pump through bearings 52 and 54. The outer end of the drive shaft 28 of the motor is rotatably supported at the housing 26 of a motor through a bearing 62. The casing 16 of the rotary pump and the housing 26 of the motor are integrally intercoupled in series through a joining member 70 in a state that the shaft of the casing 16 where the axis of the rotary shaft 18 is arranged and the shaft of the housing 26 where the axis of the drive shaft 28 is arranged are caused to coincide with each other.
