Abstract
In an attachment structure of an EA component, the EA component composed of a synthetic resin such as rigid urethane foam is attached to a trim serving as a member, with a first locking part therebetween. The first locking part includes a cylindrical part, an anchor, a flange, and a plurality of projections. The anchor has a flange shape extending from the rear end of the cylindrical part toward the outside. The flange extends from the leading end of the cylindrical part toward the outside. The projections protrude from the leading end of the cylindrical part in the direction parallel to the axis of the cylindrical part. The EA component is attached to the trim by setting the EA component on the trim while the projections are inserted in an opening.

An attachment structure of an EA component for attaching the EA component to a member, wherein:
- the EA component is attached to the member by engaging a first locking part that is integrated with the EA component with a second locking part provided in the member;
- the EA component comprises a urethane foam;
- the first locking part is integrated with the urethane foam;
- and
- the first locking part comprises a projection that engages with the second locking part and a surrounding wall that surrounds the rear end portion of the projection.
An attachment structure of an EA component for attaching the EA component to a member, wherein:
- the EA component is attached to the member by engaging a first locking part that is integrated with the EA component with a second locking part provided in the member;
- the first locking part comprises a projection that engages with the second locking part and a surrounding wall that surrounds the rear end portion of the projection;
- and
- a base of the first locking part is embedded in the EA component.
A locking piece for attaching an EA component comprising:
- a base embedded in the EA component;
- a flange provided at one end of the base;
- a plurality of projections projected from the flange, the projections being able to be resiliently deformed, and the projections being inserted in an opening for attaching the EA component;
- claw parts provided on the side face of the projections, the claw parts being able to be engaged with the edge of the opening;
- and
- a surrounding wall projected from the flange in the same direction as that of the projections, the surrounding wall surrounding the rear end portion of the projections.
