As shown in the figure, the dial knob 21 is inserted into the volume shaft 26 to be fixed by the bolt 23.

Therefore, when the dial knob 21 of the volume forcibly fixed by the bolt 23 as described above is used for a long time, the angle set by external vibration is changed, and the angle is changed even in frequent contact with other objects around it.

In addition, since the dial knob 21 and the scale indicator (not shown) shown in FIG. 5 are not integrated with the conventional compact timer or the temperature controller, an error occurs with the dial knob 21 according to the scale alignment. Through the central portion of the dial knob 21, the volume cover 25 and the volume shaft 26 inside the cover is visually complemented by covering a separate cover.

The present invention was devised to solve the above drawbacks, and it is integrated with the graduation indicator in the transparent handle body so that the number of parts can be reduced to only one so as to reduce the error caused by the alignment and shorten the assembly time with the internal volume. Its purpose is to provide the dial knob of the small timer or temperature controller that can be set smoothly with small force without setting the angle of change.

The dial knob of the present invention for achieving the above object, the center of the volume shaft 6 and the circular groove 17 is installed on the front of the small timer case 15, the inner circuit board and the rear plug is installed, the In the small timer in which the minimum angle look point 10 and the maximum angle look point 12 are formed at the bottom center of the circular groove 17 to which the dial 4 of the silk screen is attached, the volume shaft 6 And the transparent handle body (1) coupled to the circular groove (17) is formed on the inside and outside of the front center uneven parts (3, 3 '), the bottom of the graduation indicator (16) 11) and the minimum and maximum angle projections 13 and 14 on the left and right sides thereof are installed, and three force guides 7 and three look guides 8 are installed in a circle around the shaft indentation part 2 in the rear center.
