The support frame 3 is formed so that a plurality of support portions (not shown) are separated from each other in the left-right direction. The support frame 3 can support the instrument panel 9 briefly shown in FIG. 1 by the support portions thereof. The support frame 3 may be capable of supporting a steering mechanism (not shown) together with the instrument panel 9.

The left part of the dash panel 7, the left side frame 2 and the left part of the support frame 3 have the same configuration as the right part of the dash panel 7, the right side frame 2 and the right part of the support frame 3. Therefore, the illustration and description will be omitted.

<Details of the assembly configuration of the support frame with respect to the side frame>
In the vehicle body 1 having the above-described configuration, the dash panel 7, the side frame 2, and the support frame 3 are manufactured at a plurality of parts factories, and are often connected to each other at an assembly factory. Therefore, the manufacturing variations of the dash panel 7, the side frame 2 and the support frame 3 may differ in each component factory, and if no measures are taken, the positioning accuracy of the support frame 3 with respect to the side frame 2 will be affected. There is a risk.

Therefore, in the vehicle body 1, the connecting portion 30 fixed to the right end of the support frame 3 is connected to the connected portion 20 of the right side frame 2 by the configuration described below.

The configuration in which the connecting portion 30 fixed to the left end of the support frame 3 is connected to the connected portion 20 of the left side frame 2 is the same configuration as that of the right connecting portion 30 and the connected portion 20. Therefore, the illustration and description will be omitted.

As shown in FIG. 2, the connecting portion 30 has a fastening portion 31 and a positioning convex portion 40.

The fastening portion 31 includes a fastening wall 32 and connecting walls 33L and 33R. The fastening wall 32 has a substantially rectangular flat plate shape in which the length in the vertical direction is larger than the length in the horizontal direction. Fastening holes 32A and 32B are formed so as to penetrate in the front-rear direction in the upper portion and the lower portion of the fastening wall 32.

The connecting wall 33L bends from the left end edge of the fastening wall 32 and projects backward. The connecting wall 33R bends from the right end edge of the fastening wall 32 and projects backward. The right end of the support frame 3 is inserted through the connection walls 33L and 33R, and they are joined by welding or the like, so that the fastening portion 31 is fixed to the right end of the support frame 3.

As shown in FIGS. 2 and 3, the positioning convex portion 40 has a flat plate shape in which the length in the front-rear direction is larger than the length in the vertical direction. The front end portion of the positioning convex portion 40 has a tapered shape. A connection recess 43 is formed at the upper end edge of the positioning protrusion 40. The connection concave portion 43 is recessed downward at a position close to the rear end of the positioning convex portion 40 so as to draw an arc consistent with the outer cylinder surface of the support frame 3.

By welding the connection recess 43 to the outer cylinder surface of the support frame 3, the positioning convex portion 40 is fixed to the right end of the support frame 3 at a position separated to the left from the connection wall 33L of the fastening portion 31.

The positioning convex portion 40 has a flat surface 41 extending downward and substantially horizontally. The flat surface 41 is accurately cut out at the lower end edge of the positioning convex portion 40 from the substantially center to the rear end in the front-rear direction by cutting or the like. In this embodiment, the length of the flat surface 41 in the left-right direction is the same as the plate thickness of the positioning convex portion 40.

As shown in FIG. 2, the connected portion 20 has pedestal surfaces 25A and 25B, a positioning shaft 21, a regulation shaft 22, an adjusting member 50, and a fixing means 29.

The pedestal surfaces 25A and 25B are formed on the upper portion and the lower portion of the rear wall 27 of the connected portion 20. The pedestal surfaces 25A and 25B are flat surfaces extending in the vertical direction and the horizontal direction, respectively. The pedestal surfaces 25A and 25B are flush with each other. A screw hole 26A is recessed in the pedestal surface 25A. A screw hole 26B is recessed in the pedestal surface 25B.

The positioning shaft 21, the regulating shaft 22, the adjusting member 50, and the fixing means 29 are fixed to the side wall 28 facing the left of the connected portion 20, respectively.

The positioning shaft 21 is a cylindrical shaft centered on an axis X1 extending in the vehicle width direction. The positioning shaft 21 is at substantially the same height as the pedestal surface 25B located below, and protrudes to the left from the side wall 28.

The regulation shaft 22 is a cylindrical shaft extending in parallel with the positioning shaft 21. The regulation shaft 22 projects to the left from the side wall 28 at a position separated upward from the positioning shaft 21. As shown in FIGS. 3 and 4, the vertical distance between the positioning shaft 21 and the regulation shaft 22 is set to be somewhat larger than the vertical length of the positioning convex portion 40.

The fixing means 29 is a substantially rectangular plate-shaped small piece fixed to the side wall 28 at a position separated downward from the positioning shaft 21. A rack gear 29G is formed on the upper end edge of the fixing means 29. The rack gear 29G is formed so that a plurality of gear teeth are arranged in the front-rear direction and each gear tooth projects upward.

As shown in FIG. 2, the adjusting member 50 has a cam portion 51, a dial portion 52, and a through hole 50H. The dial portion 52 is integrally provided with the cam portion 51 in a state of being adjacent to the cam portion 51 from the right. The through hole 50H penetrates the cam portion 51 and the dial portion 52 with the axis X1 as the center. By inserting the positioning shaft 21 into the through hole 50H, the adjusting member 50 is rotatably supported by the positioning shaft 21.

As shown in FIG. 3, the cam portion 51 is a cylindrical shaft on which a cylindrical first outer peripheral surface 51A eccentric with respect to the axis X1 is formed. Let B1 be the length at which the center of the cam portion 51 is eccentric with respect to the axial center X1.

The distance A1 of the first outer peripheral surface 51A, which extends in the circumferential direction of the axial center X1 and is separated from the axial center X1 in the radial direction, changes in a range from A1 (min) to A1 (max).

The dial portion 52 is a cylindrical shaft on which a second outer peripheral surface 52A centered on the axis X1 is formed. The outer diameter of the dial portion 52 is set to be larger than the outer diameter of the cam portion 51. The length of the dial portion 52 in the axial center X1 direction is set smaller than the length of the cam portion 51 in the axial center X1 direction. A plurality of gear teeth are formed on the entire circumference of the second outer peripheral surface 52A. That is, the dial portion 52 has a spur gear shape.

The adjusting member 50 in the state shown in FIG. 2 is moved to the right, the positioning shaft 21 is shallowly inserted into the through hole 50H, and the adjusting member 50 supported by the positioning shaft 21 is rotated. Then, after the rotational posture of the adjusting member 50 is arbitrarily determined in the range of 0 ° to 360 °, the positioning shaft 21 is completely inserted into the through hole 50H of the adjusting member 50. As a result, as shown in FIG. 1 and the like, the rack gear 29G of the fixing means 29 engages with the second outer peripheral surface 52A of the dial portion 52.

In this way, as shown in FIGS. 3 to 5, the adjusting member 50 can be fixed to the side wall 28 of the connected portion 20 in an arbitrary rotating posture by the fixing means 29. The distance D1 in which the portion of the first outer peripheral surface 51A located directly above the axial center X1 is radially separated from the axial center X1 changes in the range from D1 (min) to D1 (max).

As shown in FIG. 5, D1 (max) −D1 (min) = B1 × 2.

<Effect>
The procedure for connecting the connecting portion 30 to the connected portion 20 will be described. For each of the dash panel 7, the side frame 2 and the support frame 3, the manufacturing variation of each component factory is grasped. Then, by changing the rotational posture of the adjusting member 50 around the axial center X1, the portion of the first outer peripheral surface 51A located directly above the axial center X1 is the axial center X1 according to the manufacturing variation of each component factory. A distance D1 is set so as to be separated in the radial direction from the above, and the adjusting member 50 is fixed by the fixing means 29.

Next, as shown in FIG. 2, the connecting portion 30 separated from the connected portion 20 is moved to the position shown in FIG. Then, when the fastening wall 32 of the fastening portion 31 is brought into contact with the pedestal surfaces 25A and 25B of the connected portion 20, the positioning convex portion 40 is in a state of facing the side wall 28 of the connected portion 20 from the left. In this state, the positioning shaft 21 and the regulation shaft 22 project toward the positioning convex portion 40 of the connecting portion 30.

At this time, for example, as shown in FIGS. 3 and 4, the flat surface 41 of the positioning convex portion 40 abuts on the first outer peripheral surface 51A of the adjusting member 50 from above, so that the right end of the support frame 3 becomes the side frame 2. On the other hand, it is positioned accurately in the vertical direction. The regulation shaft 22 abuts on the upper end of the positioning convex portion 40 when the position of the positioning convex portion 40 shifts too upward, and regulates the positioning convex portion 40 so as not to exceed the upper limit position.

Then, as shown in FIG. 1, two bolts 3B and 3B are inserted into the fastening holes 32A and 32B of the fastening wall 32 and screwed into the screw holes 26A and 26B of the pedestal surfaces 25A and 25B. As a result, the connecting portion 30 fixed to the right end of the support frame 3 is connected to the connected portion 20 of the right side frame 2. Although illustration and description are omitted, the connecting portion 30 fixed to the left end of the support frame 3 is also connected to the connected portion 20 of the left side frame 2 in the same manner.

In this way, in the vehicle body 1, the support frame 3 can be accurately positioned in the vertical direction with respect to the side frame 2 by using the adjusting member 50.

As a result, tuning work such as repairing the mold and adjusting the prototype at each parts factory can be simplified or omitted, so that the cost for repairing the mold and adjusting the prototype can be reduced and the time required for the tuning work can be reduced. Can be shortened.

Therefore, in the vehicle body 1 of the first embodiment, it is possible to shorten the time until the start-up of production and reduce the production cost. Further, in the vehicle body 1, it is possible to suppress variations in the positioning of the instrument panel 9 supported by the support frame 3. Further, in the vehicle body 1, it is possible to suppress a problem that the design surface of the instrument panel 9 and the design surface of the trim of the side door (not shown) are displaced in the vertical direction.

Further, in the vehicle body 1, since the adjusting member 50 has the cam portion 51 and the dial portion 52, the adjusting member 50 can be easily adjusted to a desired rotation posture by pinching the dial portion 52. Then, the rack gear 29G of the fixing means 29 fixed to the side wall 28 of the connected portion 20 engages with the second outer peripheral surface 52A of the dial portion 52, so that the adjusting member 50 can be easily fixed in its rotational posture.

(Example 2)
In the vehicle body of the second embodiment, the cam portion 51 of the adjusting member 50 according to the vehicle body 1 of the first embodiment is changed to the cam portion 251 shown in FIG. Other configurations of the second embodiment are the same as those of the first embodiment. Therefore, the same components as those in the first embodiment are designated by the same reference numerals, and the illustration and description thereof will be omitted or simplified.

The first outer peripheral surface 251A of the cam portion 251 has a shape that extends spirally from one end to the other end and has a step between one end and the other end when viewed along the axial center X1 direction.

In the first outer peripheral surface 251A of the cam portion 251 the distance A2 at which the portion located directly above the axial center X1 is radially separated from the axial center X1 changes in the range from A2 (min) to A2 (max).

In the vehicle body of the second embodiment having such a configuration, the flat surface 41 of the positioning convex portion 40 abuts on the first outer peripheral surface 251A of the cam portion 251 of the adjusting member 50 from above, so that the support frame 3 is brought into contact with the side frame 2 It can be positioned accurately in the vertical direction.

Therefore, in the vehicle body of the second embodiment, as in the vehicle body 1 of the first embodiment, it is possible to shorten the time required to start manufacturing and reduce the manufacturing cost. Further, also in this vehicle body, as in the vehicle body 1 of the first embodiment, the variation in the positioning of the instrument panel 9 supported by the support frame 3 can be suppressed, and the design surface of the instrument panel 9 and the side door (not shown) It is also possible to suppress the problem that the design surface of the trim is displaced in the vertical direction.

In the above, the present invention has been described in accordance with Examples 1 and 2, but the present invention is not limited to the above Examples 1 and 2, and can be appropriately modified and applied without departing from the spirit thereof. Needless to say.

In the first and second embodiments, the connecting portion 30 has the fastening portion 31 and the positioning convex portion 40, but the present invention is not limited to this configuration. The connecting portion may have any shape as long as it has a flat surface that abuts on the first outer peripheral surface from above.

The first outer peripheral surface may be an ellipse or an oval when viewed along the axial direction.

In the first and second embodiments, the fixing means 29 having the rack gear 29G is fixed to the side wall 28, but the present invention is not limited to this configuration. For example, the fixing means may be supported by the side frame so as to be displaceable between a position where it engages with the second outer peripheral surface and a position where it is separated from the second outer peripheral surface and allows rotation of the adjusting member. ..
