embedding an insert member formed of steel material in the opening; placing a side sill inner portion and a side sill outer portion oppositely to each other so that the insert member, the inner reinforcement and the outer reinforcement are disposed between the side sill inner portion and the side sill outer portion, the side sill inner portion and the side sill outer portion being formed of steel material; welding the side sill inner portion and the side sill outer portion to the insert member; and joining the inner reinforcement, the outer reinforcement, the side sill inner portion and the side sill outer portion with the side body structure of the vehicle, a reinforcement member that includes the inner reinforcement and the outer reinforcement being configured a hollow structure. ### Claim 2 (depends on 1) The manufacturing method for a side body structure of a vehicle of claim 1, wherein the embedding the insert member comprises: inserting a pre-embedding insert member into the opening, the pre-embedding insert member having a thickness greater than a thickness of the superposed reinforcement portions such that the pre-embedding insert member includes a protruding portion, and removing the protruding portion and fitting the pre-embedding insert member in the opening so as to be the insert member embedded in the opening. ### Claim 3 (depends on 2) The side body structure of a vehicle of claim 2, wherein the insert member is embedded in the opening by applying a plastic deformation force to the pre-embedding insert member such that the insert member is held in the opening by a compressive stress. ### Claim 4 (depends on 1) The manufacturing method for a side body structure of a vehicle of claim 1, wherein the embedding the insert member comprises: inserting a pre-embedding insert member into the opening, the pre-embedding insert member having an outer diameter greater than an inner diameter of the opening, and driving the pre-embedding insert member into the opening and fitting the pre-embedding insert member in the opening so as to be the insert member embedded in the opening. ### Claim 5 (depends on 1) The manufacturing method for a side body structure of a vehicle of claim 1, wherein the insert member is embedded in the opening by applying a plastic deformation force to the insert member such that the insert member is held in the opening by a compressive stress. ### Claim 6 (depends on 1) The manufacturing method for a side body structure of a vehicle of claim 1, wherein the welding the side sill inner portion and the side sill outer portion comprises joining the side sill inner portion and the side sill outer portion to the insert member by spot welding with a spot welding apparatus, and wherein during the welding the side sill inner portion and the side sill outer portion, the insert member is set such that a center of the insert member is located on a center line between electrodes of the spot welding apparatus, the method further comprising clamping the side sill inner portion and the side sill outer portion between the electrodes of the spot welding apparatus. ### Claim 7 (depends on 1) The manufacturing method for a side body structure of a vehicle of claim 1, wherein the welding the side sill inner portion and the side sill outer portion comprises joining the side sill inner portion and the side sill outer portion to the insert member by spot welding with a spot welding apparatus. ### Claim 8 A side body structure of a vehicle comprising: a reinforcement member, of a side sill of the vehicle, comprising an inner reinforcement and an outer reinforcement superposed to the inner reinforcement, and configured a hollow structure the inner reinforcement and the outer reinforcement including any one of aluminum alloy and carbon fiber reinforced composite material; and a side sill member comprising a side sill inner portion and a side sill outer portion disposed oppositely to the side sill inner portion across the reinforcement member, the side sill inner portion and the side sill outer portion being formed of steel material; wherein the reinforcement member includes a superposed portion that the inner reinforcement and the outer reinforcement are superposed and an opening that penetrates the inner reinforcement and the outer reinforcement, and wherein an insert member formed of steel material is embedded in the opening, and is fixedly welded to the side sill inner portion and the side sill outer portion. ### Claim 9 (depends on 8) The side body structure of a vehicle of claim 8, wherein a thickness of the insert member is substantially equal to a thickness of a superposed reinforcement portions formed by superposing the inner reinforcement and the outer reinforcement. ### Claim 10 (depends on 8) The side body structure of a vehicle of claim 8, wherein a thickness of the insert member is equal to or greater than a thickness of a superposed reinforcement portions formed by superposing the inner reinforcement and the outer reinforcement.
