FIG. 1 is a perspective view of an essential part showing an upper body structure of a vehicle as one embodiment of the present invention. FIG.
FIG. 2 is a cross-sectional view of a main part taken along line AA ′ of FIG. 1.

FIGS. 1 and 2 show an upper vehicle body structure according to this embodiment in which a roof reinforcement 1 extending in the left-right direction (short direction) of the vehicle and a side roof rail extending in the front-rear direction (longitudinal direction) of the vehicle. The state after the roof panel 4 is disposed in a post-process so as to be disposed at a predetermined position and further cover the upper body structure,
The side roof rail is formed by joining a roof rail outer 2 and a roof rail inner 3.

It is assumed that the side roof rails are joined by a general method before the positioning step (temporary assembling step) with the roof reinforcement 1 described below. Is omitted. In addition, a general method is also used for joining the roof panel 4 performed in a later step, and the description in this embodiment is omitted.

As shown in FIGS. 1 and 2, the end of the roof reinforcement 1 is supported above the roof rail outer 2 by a joint surface 12 with the roof rail outer 2. Hereafter, Roof Reinforcement 1
The structure of the joint between the outer rail 2 and the roof rail 2 will be described.

FIG. 3 is a front view of a roof reinforcement according to an upper vehicle body structure of a vehicle according to one embodiment of the present invention. FIG. 4 is a plan view of a roof reinforcement according to an upper vehicle body structure of a vehicle as one embodiment of the present invention. Both figures show the overall shape of the roof reinforcement 1 shown in FIGS. 1 and 2.

The contact surface 11 cuts the vicinity of the center position of the end of the roof reinforcement 1 inward from the end with a width of L1 (= L2) in the vehicle front-rear direction, and then vertically cuts the cut portion. When the roof reinforcement 1 is provided on the side roof rail as shown in FIG. 2, the roof reinforcement 1 comes into contact with the end of the side roof rail in the vehicle inward direction. Thereby, it is possible to prevent the roof reinforcement 1 from moving in the vehicle left-right direction, that is, to easily perform the positioning in the vehicle left-right direction.

FIG. 5 is a plan view of a main part of a side roof rail (roof rail outer 2) according to an upper body structure of a vehicle as one embodiment of the present invention, in a state before a roof reinforcement 1 is provided. Is shown.

As shown in FIG. 1, the side roof rail (roof rail outer 2) is provided at a plurality of locations where the roof reinforcement 1 is to be disposed, at a joint surface 12 of the roof reinforcement 1 and at a location in the vicinity thereof. Two contact surfaces 21 are formed for each location.
The width L1 of the contact surface 11 is between the two joining surfaces 21.
(= L2), a distance L3 slightly wider than
The contact surface 11 of the roof reinforcement 1 is arranged at the separated portion. This prevents the roof reinforcement 1 from moving in the vehicle longitudinal direction,
That is, positioning in the vehicle front-rear direction can be easily performed.

Further, in the shape of the joining surface 21, the shape on the side where the contact surface 11 is provided is cut obliquely as can be seen from FIGS. When the roof reinforcement 1 is transferred to a predetermined position on the roof rail outer 2, the roof reinforcement 1 can be used as a guide for movement in the vehicle front-rear direction, and the contact surface 11 is provided at a space between the two joint surfaces 21. It can be easily positioned.

As described above, according to the present embodiment, when the roof reinforcement 1 is transferred to a predetermined position on the roof rail outer 2, the shapes of both ends of the roof reinforcement 1 and the roof rail outer 2 are used. Since the shapes of the two separated joint surfaces 21 provided in the above are assembled together, these shapes themselves act as a positioning function mutually, and therefore, it is possible to provide an upper body structure of a vehicle in which positioning is easy. Thereby, even when performing automatic assembly of the production line, highly accurate assembly can be easily performed within a predetermined tact time range.

<Modification of Embodiment> In the above-described embodiment, the contact surfaces 1 at both ends of the roof reinforcement 1 are provided.

2 are formed to have different widths, and the distance L3 is formed to have different widths in the left and right side roof rails (the roof rail outer 2) according to the width of the contact surface 11 thereof. Thus, in addition to obtaining the same effects as those of the above-described embodiment, when the roof reinforcement 1 is improperly transferred at the time of assembly, the contact surface of one end of the roof reinforcement 1 is provided. 11 may not be disposed between the two joining surfaces 21, and may cause a state of being stuck at an upper portion of the joining surface 21 (a state in which the joining surface 21 does not contact any part other than the lower end of the contact surface 11). Therefore, the operator can easily visually recognize that the transfer direction of the roof reinforcement 1 is incorrect, and if the machine is an automatic machine such as a robot, the roof reinforcement 1 Can be easily detected on the basis of the output value of the tilt angle detection encoder of the hand holding the hand.

FIG. 6 is a side view of a roof reinforcement according to a second modification of the embodiment of the present invention, which relates to an upper body structure of a vehicle.

In the second modified example, the shape of the lower end of the contact surface 11A provided at both ends of the roof reinforcement 1A is formed into an obliquely cut shape as shown in FIG. Accordingly, in addition to obtaining the same effects as those of the above-described embodiment, when the roof reinforcement 1A is transferred to a predetermined position on the roof rail outer 2, it can be used as a guide for moving the vehicle up and down. Thus, the contact surface 11A can be more easily positioned at the space between the two joining surfaces 21.
