The lengths in the axial direction are shortened by the parts that have escaped and overlapped each other.

  As a result, the impact load can be absorbed by the breakage of the rod-like knob 40 of the meter 14. Further, since the movement of the steering column 16 to the front of the vehicle body is not suppressed by the rod-shaped knob 40, the impact load received from the steering wheel 12 by the driver colliding with the steering wheel 12 can be reduced.

  In the above embodiment, as shown in FIG. 3, the weakened portion 42 of the rod-like knob 40 is formed by making the shaft diameter thinner (groove) than other parts, but instead of this, FIG. As shown, the weakened portion 42 of the rod-shaped knob 40 may be formed by a plurality of slits 44 that penetrate the rod-shaped knob 40 in the diameter direction.

  Next, a second embodiment of the shock absorbing structure for a meter according to the present invention will be described with reference to FIGS.
