A drive coupling assembly includes a housing having a first wall, a second wall, a first end and a second end. A first aperture extends through the second wall adjacent to the first end and a second aperture extending through the second wall adjacent to the second end. The first aperture receives a motor drive shaft and the second aperture receives a sweep drive shaft. Each of the first and second apertures has one of a pair of sprocket hubs aligned therewith. A pair of drive hubs each has an opening extending therethrough and each opening engages one of the motor or sweep drive shafts. The drive hubs have a plurality of pins thereon extending into corresponding slots in the sprocket hubs. A continuous belt engages the sprocket hubs. The slots each have a length allowing limited rotation of the sprocket hubs with respect to the drive hubs.

A case that houses a chain includes a first cover member fixed to a cylinder block and a cylinder head, and a second cover member arranged on the opposite side of the cylinder block and the cylinder head from the first cover member. In an intermediate part, which is a part of a confronting wall of the first cover member between the first flange and the second flange, a cover-side rib is provided, having a height so that a distal end of the cover-side rib is not in contact with the cylinder block.
