  • Patent number: 7981189
    Abstract: The invention has a captive tooless fastener for securing the engine intake air filter. The tooless fastener comprises shaft and associated bodies. The body has two arms oriented about 180 degrees apart. The shaft is threaded through a sealing washer and an aperture in a closed end cap of the air filter. The shaft is expanded so it cannot be removed from the end cap. The body's threaded inner diameter mates with a threaded portion of a central shaft in an air filter housing. The body's arms are rotated to screw the fastener and the shaft of the housing together. When tightened, the sealing washer closes the aperture. To remove the air filter, the fastener is unscrewed from the shaft of the housing and in the shaft floats in the aperture. A person in the field can remove the air filter by inserting fingers under the arms and pulling.

  • Patent number: 7926378
    Abstract: A rack shaft is supported in an inner peripheral portion of a tubular housing of a gear housing via a rack bush. An inner peripheral portion of the rack bush is formed as a peripheral surface approximately similar to a circle in which a peripheral surface constituted by a large circular arc and a peripheral surface constituted by a small circular arc are continuously provided. The rack shaft is not in contact with the peripheral surface constituted by the large circular arc, and the peripheral surface constituted by the small circular arc is formed as a support portion of the rack shaft. The support of the rack shaft by the peripheral surface constituted by the small circular arc is not accomplished when a load applied to the rack shaft is nothing or low, but is accomplished when the load is high. Further, an engaging convex portion acting as a positioning and rotation prevention for the bush is provided in an outer peripheral portion of the rack bush.
