でカバーされている。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A side door structure for an automobile according to a first embodiment of the present invention will be described with reference to FIGS. 1 and 2. Side door 1
As is well known, a belt molding 6 with a weather strip 6a that comes into contact with the door glass 7 is attached to the flange portion 2a at the upper edge of the outer panel 2. A bulged portion 10 projecting inward from the normal general surface toward the passenger compartment is integrally formed by press molding at the upper end portion of the inner panel 4 in the height region of the belt molding 6 corresponding to the door open end side for the occupant. ing. That is, the upper and lower surfaces 11 and 12, which are the peripheral surfaces, and the side surfaces 13 and 14 on both sides, respectively, are inclined inward toward the front surface 15 and are formed in a rectangular truncated pyramid shape. The front surface 15 bites in the vehicle width direction of the bulging portion 10 so that the front surface 15 buckles when an impact load of a predetermined level or more is applied from the inside of the vehicle interior. U-shaped long hole-shaped notches 16 and 16a which are vertically cut
Are formed for strength adjustment. The bulging portion 10 as a cushioning body formed in this manner is used for the door trim 8 of the corresponding shape.
Is covered by.

In the vicinity of both ends of the front surface 15 of the bulging portion 10 in the vehicle front-rear direction, U-shaped notches 26 and 26a for adjusting the strength, which cut into the upper and lower surfaces 11 and 12 and are vertically cut, are formed, respectively. ing. When the occupant collides, the front surface 15 and the upper and lower surfaces 11, 12 between the front surface 15 are buckled due to the notches 26 and 26a on both sides thereof. It is also applied to a rectangular bulge that is not a truncated pyramid, and when the collision load direction is obliquely applied from above or below, the upper and lower surfaces 11,
12 buckles in a corresponding direction with bending deformation.

A plurality of elongated hole-shaped cutouts 36 for strength adjustment which are intermittently connected to the peripheral surfaces of the upper and lower surfaces 11 and 12 and the side surfaces 13 and 14 on both sides of the bulging portion 10 in the vehicle width direction. Are formed. As a result, when a load is applied to the front surface 15, the upper portion 10a closer to the vehicle interior than the arrangement position of the cutout portions 36 buckles, and the rear portion is depressed. Instead of the elongated hole, it is also conceivable to form another shape, for example, a circular hole-shaped notch portion intermittently into a loop shape.

A long groove 16 having a substantially semicircular cross section is formed as a bead. As a result, the load is applied to the front 15 from the vehicle width direction.
In addition, when it is added to B, it is bent and deformed by the long groove 46 as shown by a dotted line in FIG.
