摘要： A tank cap includes: a synthetic-resin cap body (20) mounted on a fuel supply port cylinder (18) of a conductive fuel tank, (T); a conductive cap shell (22) coupled to an upper part of the cap body (20); and a gasket (23) provided in the cap body (20) and in close contact with a sealing surface (18a) of the fuel supply port cylinder (18). The cap body (20) and the cap shell (22) are linked to be mutually rotatable. A ratchet mechanism (35) is mounted between the cap shell (22) and the cap body (20). An elastic contact piece (38) elastically and slidably contacting an inner peripheral surface of a cylindrical peripheral wall (22a) of the cap shell (22) is integrally projectingly provided on an outer periphery of the gasket (23). Thus, it is possible to cause static electricity carried by an operator to escape to a fuel tank through the gasket.

摘要： In a V-type engine, intake and exhaust rocker arms in each bank are arranged in a substantially inverted-V-shape in a plan view, so that side end portions of corresponding intake and exhaust push rods are positioned adjacent to each other. Slipper portions of first and second intake cam followers have end portions at one end along the axial direction of a camshaft protrude respectively in opposite directions to each other so that they face each other across an intake cam therebetween. Slipper portions of first and second exhaust cam followers have end portions at one end along the axial direction of the camshaft protrude respectively in opposite directions to each other so that they face each other across an exhaust cam therebetween. This reduces the distance between the push rods in each bank to provide a compact valve-operating device.

摘要： An engine includes a cylinder head having a valve-operating chamber. A cylinder head is coupled to a cylinder block by a plurality of fastening bolts. A head cover is coupled to the cylinder head to close the valve-operating chamber. A ventilating gap is defined between a face of the cylinder head fastened by the fastening bolts and a bottom wall of the valve-operating chamber. An operating bore is provided in the bottom wall to enable insertion of at least one of the fastening bolts and a tool for tightening the fastening bolt. A plug is integrally provided in the head cover to be liquid-tightly fitted into the operating bore. Cooling of portions around the bottom wall of the valve-operating chamber is improved, while the cylinder head can be fastened to the cylinder block from the side of the valve-operating chamber by the fastening bolts.

摘要： In an engine operated machine system including a hollow support rod connected at one end to an engine through a vibration insulator, an auxiliary weight is mounted at the other end of a crankshaft for generating a centrifugal force in the same direction as an inertia force of a piston, when the piston reaches top and bottom dead centers. Thus, it is possible to bring a center of gravity of the engine closer to the position of the vibration insulator, thereby suppressing the application of the vibration from the engine to the support rod to the utmost.

摘要： In a handheld type four-cycle engine, a valve operation mechanism includes a camshaft rotatably supported in a cylinder head so as to open and close an intake valve and an exhaust valve and a timing transmission placed on one side outside an engine main body and providing association between a crankshaft and the camshaft, and a centrifugal clutch for power output is mounted on the crankshaft on the opposite side outside the engine main body. The timing transmission and the centrifugal clutch being positioned at the two ends of the crankshaft improves the weight balance, the centre of gravity of the engine can be made as close to the central part of the crankshaft as possible, which, together with the reduced weight, can enhance the operability of the engine.

摘要： In a working engine including a bearing mounted on an outer wall of a crankcase for carrying a crankshaft, an oil seal mounted on the outer wall of a crankcase and disposed outside and adjacent the bearing, and a cooling fan which is attached to an outer end of the crankshaft adjacent the oil seal with its blades turned toward the crankcase and which has blades protruding toward the crankcase, a cylindrical protective tube is formed on an outer sidewall of the crankcase to cover ends of bosses of the cooling fan, and a foreign matter-beating piece is formed on the cooling fan 16 in proximity to an outer peripheral surface of the protective tube. Thus, even if a long foreign matter drawn in by the cooling fan such as a weed and the like has been entangled around the crankshaft, it can be beaten and loosened, or cut by the foreign matter-beating piece rotated along with the cooling fan. Therefore, it is possible to prevent the entanglement around the foreign matter around the crankshaft, thereby avoiding damage to the oil seal as a result of the entanglement.
