  • Patent number: 7762419
    Abstract: A cap has a pair of L-shaped, flexible engaging arms that extend, from the end of a cap body opposite to the direction of fitting, in the direction of fitting with a distance away from the cap body. The distal ends of the engaging arms are connected by a pair of flexible connecting bridges to surround the outer periphery of the cap body with a distance away therefrom. The cap body is fitted into a cylindrical part of a cylinder head cover and engaging projections of the pair of engaging arms are engaged with an engaging recess in the outer periphery of the cylindrical part. The engaging arms are flexed to get away from the outer periphery of the cylindrical part by pushing circumferentially middle parts of the connecting bridges to come close to each other, so that the engaging projections are disengaged from the engaging recess.

  • Patent number: 7311936
    Abstract: While a corner part 35 of a skin 7 formed between side covers 30 and 31 has a sector shape, a corner part 29 of a base material 9 also has a sector shape. When resin is charged between the skin 7 and the base material 9, the sector-shaped corner part 35 is bent under a pressure at which the resin is charged to stretch outward, thereby bringing the sector-shaped corner part 35 into absolute contact with the sector-shaped corner part 29 of the base material 9. This prevents resin leakage from between the skin 7 and the base material 9.
