の駆動装置。[Claims for Utility Model Registration] (1) The drive shaft of a pump unit attached to the output shaft of the drive motor at the tip side via a power transmission means is capable of reciprocating against axial biasing force. In a reciprocating pump drive device, the drive shaft portion of the pump portion is interlocked with each other and includes means for regulating the amount of axial movement of the drive shaft portion to enable adjustment of the stroke length of the pump portion. The power transmission means includes an eccentric cam mechanism having a pair of eccentric cam members arranged symmetrically apart from each other about the cam shaft, and the power transmission means for transmitting power to the rear of the drive shaft of the pump section with the eccentric cam mechanism interposed therebetween. What is claimed is: 1. A reciprocating pump drive device, characterized in that the end side of the reciprocating pump is pivotally supported, and the stroke length adjusting means is positioned correspondingly on the central axis of the rear end side of the drive shaft portion of the pump portion. (2) The power transmission means includes a worm provided on the output shaft side of the drive motor and a worm wheel provided on the camshaft side, and a pair of eccentric cam mechanisms that rotate eccentrically by rotation of the worm wheel. Utility model registration claim 1, characterized in that the cam members are configured to slide in symmetrical contact with the power transmission parts formed in the middle of the drive shaft part of the pump part, so that the power transmission force can be distributed. A drive device for a reciprocating pump as described in . (3) The stroke length adjustment means includes an abutting member located correspondingly along the central axis on the rear end side of the drive shaft portion of the pump section, and the abutting member is movable and adjustable along the central axis. 2. A reciprocating pump drive device according to claim 1, characterized in that the reciprocating pump drive device comprises a rotation adjustment body provided with a display scale that indicates the number of degrees.
