    摘要： There is provided a four-cycle engine which can appropriately circulate oil in an engine regardless of a tilted condition with a simple structure. A crankcase (4) of a four-cycle engine (1) has a crank room (41) which rotatably supports a crankshaft (10) and an oil room (42) which is provided adjacent to the exterior of the crank room (41). The crankcase (4) also has partition walls (43) and (44) which partition the interior of the crankcase (4) into the crank room (41) and the oil room (42), respectively, and a communication path (45) which communicates the crank room (41) with the oil room (42). The partition walls (43) and (44) each has a cross section formed in a substantially V shape, and the communication path (45) is formed at an apex between the partition walls (43) and (44).

    摘要： An impact force is transmitted to a tip end tool due to the changes of the air pressure within an air chamber generated by the reciprocal operation of the piston within a striker. The attachment portion of a tip end tool holding member for holding the tip end tool to a cylinder casing is sandwiched between buffers disposed in the two directions of the axial direction of the tool thereby to elastically support the tip end tool holding member to be movable in the two directions of the axial direction of the tool.
