The anti-slip portion 102 is formed of fine irregularities, and increases the frictional force generated between the finger that comes into contact with the operation surface 101 during operation.

  When the operation knob 100 is operated, the operation knob 100 is held on the fingertip by the friction force generated between the finger and the operation surface 101 and operated. For this reason, when the frictional force is small, the operation knob 100 cannot be held, slipping off from the fingertips, or the force is difficult to put in, resulting in poor operability.

  Further, in order to increase the frictional force, it is conceivable to make the unevenness of the anti-slip part 102 larger or deeper, but in this case, an operator who touches the anti-slip part 102 is uncomfortable, There was a concern that the appearance was uncomfortable.

[Operation knob hooking action]
7A and 7B show an operation knob lowering operation in the wind direction adjusting device of the first embodiment, where FIG. 7A is a sectional view of the entire wind direction adjusting device, and FIG. 8A and 8B show an operation knob raising operation in the wind direction adjusting device of the first embodiment, where FIG. 8A is a cross-sectional view of the entire wind direction adjusting device, and FIG.

  In the wind direction adjusting apparatus 1 according to the first embodiment, in order to lower the operation knob 10 downward, first, as shown in FIG. 7A, the operator's fingertip S is pressed against the operation surface 11 of the knob body 10a. The operation surface 11 is formed with a knob outer surface 12 and a curved indent surface 14 having a recess 13 with respect to the knob outer surface 12 and provided with a non-slip portion 15.

  Therefore, as shown in FIG. 7B, the fingertip S contacts the anti-slip portion 15 in the curved dent surface 14 (C portion), and dents generated between the curved dent surface 14 and the knob outer surface 12. The lower side of the step 13 is contacted (D portion). In this state, the finger is lowered and the operation knob 10 is lowered. Thereby, each wing | blade 6a of the horizontal louver 6 rotates all at once, and closes the front surface opening 3a.

  Thus, by lowering the curved concave surface 14 provided with the anti-slip portion 15 from the knob outer surface 12 by one step, the fingertip S is caught by the concave step 13 and the finger catching property with respect to the operation surface 11 is improved. For this reason, even if the frictional force generated between the fingertip S and the anti-slip portion 15 is weak, the fingertip S becomes difficult to slip from the operation surface 11 and the operability can be improved.

  In order to raise the operation knob 10 upward, first, as shown in FIG. 8A, the operator's fingertip S is pressed against the operation surface 11 of the knob body 10a. As a result, as shown in FIG. 8B, the fingertip S comes into contact with the anti-slip portion 15 in the curved concave surface 14 (E portion) and is generated between the curved concave surface 14 and the knob outer surface 12. It contacts (F part) the upper side of the dent level | step difference 13. FIG. In this state, the finger is raised upward and the operation knob 10 is raised. Thereby, each wing | blade 6a of the horizontal louver 6 rotates all at once, and the front surface opening 3a is open | released.

  As described above, when the operation knob 10 is raised and operated, the fingertip S is recessed and caught on the step 13, so that the finger holdability is improved. For this reason, even if the frictional force generated between the fingertip S and the anti-slip portion 15 is weak, the fingertip S becomes difficult to slip from the operation surface 11 and the operability can be improved.

FIG.

  Here, in the wind direction adjusting apparatus 1 according to the first embodiment, the curved concave surface 14 is curved along a direction orthogonal to the operation direction of the operation knob 10. For this reason, as shown in FIG. 9, the curved indentation surface 14 can follow the shape of the fingertip S in contact from the offset direction. For this reason, the contact area between the anti-slip portion 15 and the fingertip S is increased, the frictional force can be increased, the slip is less likely, and the operability can be improved.

  Further, when the lateral louver 6 is opened, even if the operation surface 11 of the operation knob 10 faces the vehicle compartment, the curved dent surface 14 is curved, thereby reducing the visual sensation of the operation surface 11. be able to. For this reason, the dent level | step difference 13 between the knob outer shape surface 12 and the curved dent surface 14 becomes inconspicuous, and it looks like a flat shape, and can improve the design property.
