Abstract

The present invention provides a reciprocal pump apparatus that can reduce the bending stress on the crankshaft. The reciprocal pump apparatus comprises a driving portion 30, a crankshaft for a piston 14 of the reciprocal pump 12, a decelerating portion 42 that is adjacently provided to the driving portion, a big gear 44 provided on the crankshaft and a small gear 46 engaging with the big gear 44 and provided on an input shaft 48 for inputting power. In the reciprocation pump apparatus 10, a first bearing 58 and a second bearing 56 that can be used to support and rotate the input shaft are provided at a side opposite to the driving portion 30 and supporting the input shaft 48 in a suspension arm fashion, so that the small gear 46 is adjacent to the driving portion and the whole length of the crankshaft can be shorten, to reduce the bending stress.
