Zusammenfassung:	A drive arrangement for a portable reciprocating power saw or the like including a crankshaft having a pair of closely spaced opposed crank throws and connecting rods attached to each throw. One connecting rod is connected to a tubular reciprocating blade drive member and the other connecting rod is connected to a cylindrical counterweight slidably housed in telescoping relationship within the tubular blade drive member. The saw blade drive member and counterweight reciprocate in opposite directions along a common axis and the saw blade drive member also serves as a bearing support for the counterweight.
