The multi-sectional driveshaft for a multi-unit rotary piston mechanism has a plurality of driveshaft sections of identical configuration, arrangted co-axially with the end portion of one section telescopically engaging the end portion of a next adjacent section. Each section comprises an elongated body having an axial bore therethrough and an eccentric portion between the opposite end portions of the elongated body. One end portion is of reduced size with a shoulder extending normal to the axial bore. The other end portion of each section has a portion of the axial bore adjacent thereto of a size and configuration complementary to the one end portion for receiving and engaging the one end portion of the next adjacent section. A tie-bolt extends co-axially through the bores of the sections for securing the sections in end-to-end engagement with each other for torque transmission and with the other end portion of a section in abutment against the shoulder of said one end portion of the next adjacent driveshaft section. The bore of each section may be provided with an internally threaded portion adapted to receive various tool means for assembly and disassembly of the driveshaft sections.
