DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a front view of a steering column cover device showing an embodiment in which the present invention is applied to a right-hand drive vehicle, as viewed from the passenger compartment side, FIG. 2 is a right side view of FIG. 1, and FIG.
FIG. 4 is a front view of a steering column cover device showing an embodiment in which the present invention is applied to a left-hand drive vehicle, as viewed from the passenger compartment side.

In these figures, an upper end of a steering shaft 3 is connected to a steering wheel 2 provided above a floor 1, and an input shaft of a steering gear box provided below the floor 1 (both not shown).
And the lower end of the steering shaft 3 are connected via a sliding shaft 4 penetrating the floor 1. Here, the input shaft of the steering gear box is located outside the vehicle body from an extension of the steering shaft 3. Therefore, the sliding shaft 4 is inclined so as to be displaced outward as it goes down.

The steering shaft 3 is held by a column (not shown), and the column is covered with an upper cover 5. In addition, the center of the steering shaft 3, the column, and the upper cover 5 is located substantially on a vertical line when viewed from the front or the rear.
These are the same as in the case of the steering column cover device of the conventional cab-over type vehicle.

On the other hand, a lower cover 6 for covering the sliding shaft 4 projecting above the floor 1 is shown in FIGS.
As shown in FIG. 3, it is formed in a substantially drum shape in which the left and right widths and the front and rear widths of the central portion are narrowed. In addition, by inclining the center line of the lower cover 6 in the same direction as the center line of the sliding shaft 4, a space between the tunnel portion 7 provided in the center portion of the floor 1 and the lower cover 6 is ensured. I have to. Further, the mounting seat surface 8 of the lower cover 6 on the floor 1 is constituted by an inclined surface substantially perpendicular to the center line of the sliding shaft 4 as shown in FIGS. Reference numeral 9 denotes a dust seal for sealing a connection portion between the upper cover 5 and the lower cover 6;
Reference numerals 0 and 11 denote an accelerator pedal and a brake pedal provided on the right side of the lower cover 6, 12 and 13 denote clutch pedals and footrests provided on the left side of the lower cover 6, 14 denotes a center line of the vehicle body, and the pedals are the same as those in the conventional case. Works similarly.

In the steering column cover device for the cab-over type vehicle constructed as described above, the column holding the steering shaft 3 is covered with an upper cover, and the sliding from the lower end of the steering shaft 3 to the input shaft of the steering gear box is performed. The shaft 4 is covered with a lower cover 6. Since the connecting portion between the upper cover 5 and the lower cover 6 is covered with the dust seal 9, the appearance inside the vehicle compartment is maintained well, and the rotating portion is prevented from being exposed, thereby ensuring safety.

Also, since the lower cover 6 is attached to be inclined so as to be deviated outward as it goes down similarly to the sliding shaft 4, the tunnel portion 7 and the lower cover 6 provided at the center of the floor 1 are provided. The space between and becomes wider. For this reason, in the case of a right-hand drive vehicle, for example, the space around the clutch pedal 12 is enlarged, and the operability of the pedal 12 is enhanced.

On the other hand, when the lower cover 6 is mounted to be inclined, the lower cover 6 applied to a right-hand drive vehicle cannot be used as it is as a lower cover for a left-hand drive vehicle. However, in the present invention, the mounting seat surface 8 of the lower cover 6 on the floor 1 is formed by an inclined surface perpendicular to the center line of the sliding shaft 4. Therefore, in the case of a left-hand drive vehicle, as shown in FIG.
Is formed, the lower cover 6 used for the right-hand drive vehicle can be applied as it is, and thus, the floor 1 and the lower cover can be shared.

[0014] The left and right widths of the central portion of the lower cover 6 are set.
The inner surface of the lower cover 6
The mold configuration has been simplified by splitting the forming die up and down
Also in this case, it becomes easy to secure a predetermined draft angle,
