ている。(Technical background of the invention and its problems) Conventionally, this type of opposed type reciprocating pump, for example, the so-called "horizontal type", in which two bellows pumps are placed opposite each other in the horizontal direction and combined in a two-unit system, has been used. In the reciprocating pump, a deceleration mechanism is incorporated in the output shaft of the drive motor as a driving force transmission means for the pumping operation of the bellows that constitute the left and right pump parts, and the ! of the pump part is transmitted through this deceleration mechanism. It has a structure in which connecting rods (hereinafter simply referred to as connecting rods), which are drive shaft parts, are connected.

が大きくなり。However, in the driving force transmission means for the pumping operation in such conventional dual pump units, each drive shaft unit is reciprocated by a single rod, so the eccentric cam mechanism becomes complicated. Moreover, since the reduction mechanism consists of a combination of spur gears, the entire mechanism becomes large.

とが可能になる。(Function) That is, by having the above configuration, the present invention has the following features:
A pair of left and right pump bodies are positioned facing each other along one direction, and the drive shafts of these pump parts are formed of double rods, and a worm is provided on the output shaft of the drive motor and a worm meshed with the worm. An eccentric cam is installed in a speed reduction mechanism consisting of a wheel and rotated eccentrically.
Since the double rods forming the drive shafts of both pump parts are made to reciprocate, it is possible to give reciprocating motion to both pump parts with a single movement system using the double rods. Since the power is transmitted by decelerating it using a worm gear, the mechanism becomes simple, thereby making it possible to reduce the size and cost.
