A speed reduction device for transmitting the rotation of a drive shaft to a driven shaft in a speed reducing manner. An eccentric cam is securely mounted on the drive shaft and has a central axis eccentrically offset from a central axis of the drive shaft, and the driven shaft is rotatably mounted in eccentrically offset relation from the drive shaft by an eccentricity equal to that of the eccentric cam. The driven shaft includes a pair of opposed surface portions which are adapted to rotate in a normally clamping and circumscribing relation with respect to the eccentric cam. When the speed reduction device is used in an intake and exhaust valve timing and actuating device of an internal combustion engine, a crank shaft serves as the drive shaft, while a follower cam associated with intake and exhaust valves serves as the driven shaft.

A cutter housing for use in a power-driven lawn mower has a substantially cylindrical skirt wall and a top wall covering the upper end of the skirt wall. The top wall has a substantially central recess for accomodating the engine of the lawn mower and includes a pair of half members positioned one on each side of the recess and lying substantially flush with each other in symmetrical and contiguous relation. The cutter housing also has a rear housing portion extending rearwardly in contiguous relation to the skirt wall and the top wall, and a partition disposed in the rear housing portion and dividing the rear housing portion into two spaces. The skirt wall, the top wall, the rear housing portion, and the partition are integrally molded of synthetic resin.
