For example, the output rotary shaft of the motor and the input rotary shaft of the pump are connected by a joint. In this case, it takes a great deal of effort to carefully install the motor and the pump so that the output rotation shaft of the motor and the input rotation shaft of the pump are sufficiently aligned. In addition, even if you pay attention to such alignment and install it, some eccentricity and declination remain between both rotating shafts, and further vibration occurs in the motor and pump during operation, In order to absorb these at the joint portion, a flexible joint using a flexible member such as a spring or rubber has been conventionally used. Further, an Oldham joint is used as a joint capable of coping with eccentricity and declination.
