In a starter for internal combustion engines, a tubular pinion gear support shaft 8 is rotatably supported by a casing, and coupled to a drive shaft of a motor so as to be rotatively driven by the motor, and an annular pinion gear 3 is fitted on the pinion gear support shaft in axially slidable but rotatively drivable relationship. A push rod 9 is axially slidably received in the tubular pinion gear support shaft and provided with a free end engaged with a free end of the pinion gear for transmitting a shifting force for driving the pinion gear into meshing with a ring gear of an engine from a shift lever to the push rod. A shift spring 15 consisting of a compression coil spring is coaxially received in the pinion gear support shaft and interposed between an associated end of the shift lever and a base end of the push rod. Thus, the assembling of the starter is simplified while the action of the shift spring is stabilized, and the design of the starter is made compact.
