Adhesive injection method and structure

An adhesive injection method for injecting an adhesive for bonding an outer plate and a reinforcing member, the reinforcing member having a plurality of through holes bored through the reinforcing member in a direction intersecting a bonding surface facing the outer plate, the adhesive injection method comprising:

• positioning the outer plate and the reinforcing member;
• arranging a seal to cover a gap between the outer plate and the reinforcing member;
• and
• injecting the adhesive into the through holes in order from a first end to a second end of the bonding surface,
• wherein during the injecting, while the adhesive is injected into a first one of the through holes, when the adhesive appears through a second one of the through holes adjacent to the first one of the through holes into which the adhesive is being injected, a location at which the adhesive is to be injected is shifted from the first one of the through holes into which the adhesive is being injected to the second one of the through holes,
• wherein, during the injecting, a lid member is attached to the first one of the through holes into which injection of the adhesive has been completed, the lid member including:
• a lid body covering the first one of the through holes;
• a protrusion extending in a protruding manner in a direction from the lid body toward the outer plate;
• and
• a stopper located at a position of a predetermined length from a front end of the protrusion toward the lid body and and configured to prevent the lid member from coming off from the first one of the through holes, and
• wherein the lid member is configured to keep the thickness of the adhesive at a length defined based on the predetermined length.

• wherein the seal is a separate and discrete element with respect to the adhesive, and is configured to shape any adhesive protruding from the gap between the outer plate and the reinforcing member,
• wherein the seal is configured to form the adhesive injected during the injecting into a tapered shape tapering from the reinforcing member to the outer plate, and
• wherein the seal is a dam member which is a rigid body, and an inside of the dam member being formed in a tapered shape tapering from the reinforcing member to the outer plate.
