The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. The drawings are viewed in the direction of the reference numerals. In the following description, front, rear, left, and right are determined based on passengers, particularly drivers.
FIG. 1 is an external view of a vehicle according to the present invention. A vehicle 10 has an opening 12 at a front portion of a vehicle body 11, the opening 12 is closed by a front door 13, and along the lower edge of the opening 12. The left bumper beam 14L and the right bumper beam 14R (L is a subscript meaning R is left and R is right). The same applies to the following, and a steering handle 15 and at least one seat 16 are provided in the vehicle. . Reference numeral 17 is a front wheel, and 18L and 18R are front combination lamps.

  FIG. 2 is a layout diagram of the bumper beam and the bumper lateral movement mechanism according to the present invention. From the front part of the vehicle body frame 21, a plurality of (four in this example) bumper receiving beams 22, 23, 24, 25 are provided. It extends to the front of the car. The bumper receiving beams 22 to 25 support the left and right bumper beams 14L and 14R and the sliders 26 and 26.

The slider 26 includes a cross member 27 extending in the vehicle width direction and longitudinal members 28 and 29 that connect the cross member 27 to the left and right bumper beams 14L or 14R. The slider 26 is moved in the vehicle width direction by the bumper lateral movement mechanisms 30, 30.
The detailed structure of the bumper lateral movement mechanisms 30, 30 will be described with reference to the next figure.

  3 is a cross-sectional view taken along the line 3-3 in FIG. 2. The bumper lateral movement mechanism 30 is, for example, a large bracket 31 provided on the bumper receiving beam 23, and the large bracket 31 via a small bracket 32. An electric motor 33, a small bevel gear 34 attached to the output shaft of the electric motor 33, a large bevel gear 35 that meshes with the small bevel gear 34, and a nut member 36 that also serves as a boss of the large bevel gear 35. The bearings 37 and 37 that support the nut member 36, the bearing housings 38 and 38 that are supported by the large bracket 31 to support the bearings 37 and 37, and the feed screw that is screwed to the nut member 36, respectively. 39, and the base of the feed screw 39 is connected to the longitudinal member 29.

  When the electric motor 33 is energized and the small bevel gear 34 is rotated, the small bevel gear 34 rotates the large bevel gear 35 and the nut member 36 is rotated. Since the feed screw 39 is a non-rotating member, when the nut member 36 rotates, the slider 26 moves sideways to the position indicated by the imaginary line. Since the cross member 27 constituting the slider 26 is always mounted on the two bumper receiving beams 22 and 23, there is no fear that the slider 26 is detached from the bumper receiving beams 22 and 23.

The operation of the vehicle 10 having the above configuration will be described next.
