A method of manufacturing an insulator is provided. The insulator includes a lower member and an upper member. The lower member is placed as a second flange of the lower member is fixed in position. The upper member is then disposed on the lower member as the second flange of the upper member is fixed in position. Accordingly, the first flange of the upper member and the first flange of the lower member abut each other, and the second flange of the upper member and the second flange of the lower member abut each other. Then, the first flange of the upper member and the first flange of the lower member are swaged, and then the second flange of the upper member and the second flange of the lower member are swaged.

A vehicle bottom structure includes heat shield plate, which is arranged between a vehicle component and an exhaust pipe, and two undercovers, which are arranged on the opposite sides of the exhaust pipe in the vehicle width direction. The heat shield plate has a covering portion, two heat-shield-plate fastened portions, and two heat-shield-plate coupling portions. The covering portion covers the exhaust pipe. The heat-shield-plate fastened portions are each fastened to the corresponding one of the undercovers. The heat-shield-plate coupling portions each couple a corresponding lower end of the covering portion to the corresponding one of the heat-shield-plate fastened portions. Each heat-shield-plate coupling portion includes a section that has a shape that becomes higher toward the corresponding undercover in the vehicle width direction. The heat-shield-plate fastened portions are each located above the corresponding lower end of the covering portion.

The power unit includes an internal combustion engine that combusts air-fuel mixture in an engine body and outputs a driving force, and a motor that outputs a driving force by using electric power of an electric generator or a battery. The transmission member transmits the driving force of the power unit. The capsule structure includes a heat-insulation casing having an internal space in which the power unit and the transmission member are accommodated, and a partition wall that divides the internal space of the heat-insulation casing into at least a first partition space and a second partition space which are separated from one another. At least the engine body is disposed in the first partition space, and at least the battery is disposed in the second partition space.

A fastening device for fastening a shielding part to a fastening partner in a vibration-decoupled manner having a collar bushing that has at least one bushing core and two collars that protrude outward in a radial direction (R) and are spaced apart from each other in an axial direction (A), with the collars forming an interstice between themselves and having a bridge element, which is positioned with its radially inner region in the interstice; and the bushing core extends through an opening of the bridge element with a radial play (s),
wherein a damping element is positioned in the axial direction (A) between the collars and in the radial direction (R) between the bushing core and a radial stop of the bridge element and is dimensioned so that the radial mobility of the bridge element relative to the bushing core is limited to an effective radial play (s) that is reduced relative to the radial play (s).

An apparatus for shielding hot regions, in particular of an internal combustion engine, includes a heat shield with a through hole. The apparatus has a component, in particular a heat source, with a fastening region which has a receptacle and a shoulder which surrounds the receptacle at least partially. The shoulder extends through the through hole of the heat shield. The apparatus has a fastening element, in particular a screw, which fastens the heat shield to the fastening region, the fastening element being supported on the shoulder, extending through the through hole of the heat shield, and being fastened in the receptacle.

A heat insulating cover (cylinder-head-side heat insulating cover (30)) includes a top wall (31) and first side walls (32). The top wall (31) covers a top surface of an engine (1) that is a surface of an upper portion of the engine (1). The first side walls (32) cover respective upper portions of both side surfaces of the engine (1) in a vehicle width direction. A portion of the heat insulating cover closer to the rear of the vehicle is provided with a hinge mechanism (36) vertically rotatably supporting the upper portion of the heat insulating cover including the top wall (31). The upper portion of the heat insulating cover can be rotated, with the hinge mechanism (36) as a fulcrum, between a closed position where the engine (1) is shielded and an open position where the engine (1) is visible.

A vehicle with a capsule structure of a power unit includes the power unit and a transmission member. The power unit includes an internal combustion engine that combusts air-fuel mixture in an engine body and outputs a driving force, and a motor that outputs a driving force by using electric power of an electric generator or a battery.
