Abstract: A thin-walled light resin composition engine cover has reduced mass and thickness while retaining radiated sound reduction effects, heat resistance, and mechanical properties. The cover has an average thickness of 2.0 mm or less. The resin composition includes (a) a polyamide resin composed of essentially at least one of scrap of vehicle airbag fabric made of nylon 66 containing a copper-based stabilizer and vehicle airbag fabric recycled, (b) a modified polypropylene resin, (c) a reinforcement material, (d) a metal deactivator and a photo-thermal stabilizer, and (e) a viscosity regulator. The resin composition has a melt flow rate of not less than 40 g/10 min.

Abstract: An engine cover mounting structure comprising an engine member and an engine cover, wherein a plurality of portions to be fixed to which fixing portions provided on the engine cover are mounted are provided so as to be situated below an upper surface of a cylinder head cover of the engine member. In addition, a positioning portion is provided on the engine cover. Then, in a state where a base fixing portion is mounted or temporarily mounted to a base portion to be fixed, while the other fixing portions are not mounted to the other portions to be fixed, when the engine cover revolves about the base fixing portion, so that the positioning portion is brought into abutment with a surface of the engine member, the fixing portions other than the base fixing portion are disposed at positions facing the portions to be fixed, respectively.

Abstract: An engine cover includes an installation member, a cover body, and an installed member. The installation member is disposed on an engine. One of the installation member and the installed member includes a leg, and a head, and the other one of them includes a framed member, and an elastic member. The elastic member includes a first hole, a second hole, and a diametrically-enlarged intermediate hole. The head engages with the diametrically-enlarged intermediate hole. Moreover, the head is disposed movably toward the second hole when a downward load is applied to the cover body, thereby bringing the cover body closer to the engine.

Abstract: A mounting structure for an engine cover includes: a protruded member which has a neck and a head with a larger diameter than the neck; and a recessed member which has an external circumferential surface small diameter section to be locked to a mounting hole of a mounting seat arranged so as to be opposed to the protruded member, and a concave holding the head of the press-fit protruded member. In the protruded member, at least a portion surrounding the concave is formed solid. The head is arranged closer to a rear surface of the engine cover than the mounting hole. A compression space, which is compressed in the case in which a collision load equal to or larger than a predetermined value is applied in a front and rear direction of the engine cover, is defined between the recessed member and the rear surface of the engine cover.
