In order to achieve the above object, the present invention provides an operation knob (1) including a knob body (2) and a knob body (2).
And the knob body (2) comprises:
Either the vertical fin or the horizontal fin of the wind direction adjuster
Through-hole through which the fin passes and one side wall is opened (5)
(3) and the lower end of the side wall opening (5) of the through hole (3).
The formed overhanging shelf (5a) and the overhanging shelf (5a)
And the side wall facing the overhanging shelf (5a)
Tapered surfaces respectively formed at the upper ends of the openings (5)
(7, 8) and cover the left and right end sides of the side wall opening (5).
(6, 6)
And the linking body (10) is provided with the knob book
Body part (11) that fits into side wall opening (5) of body (2)
And the knob main body at the left and right ends of the main body (11).
The overhang flange portion (6, 6) of (2) is a step portion (13,
13) formed so as to be retained and fitted by retaining
A substantially L-shaped overhang portion (14, 14);
Undercuts formed at both upper and lower ends of 1)
(15, 16) and the overhanging flan
The projections (6, 6) fit into the overhangs (14, 14).
When the taper surface (7, 8) is
And the knob body is mutually engaged in the knob portions (15, 16).
The main body of the linking body (10) with the side wall opening (5) of (2)
(11) is configured to be fitted and accommodated.

[0008]

According to this structure, the L-shaped overhang of the link body is held and retained by the overhang flange of the knob body at the step, and the undercut portions of the knob body and the link body are engaged with each other. Thus, the linkage can be securely held, and the operation knob can be operated in any direction of up, down, left, and right without rattling, and the operation stability when the operation knob slides is improved.
