A click module which gives a feeling of click when an operation knob which is tiltably and pivotally supported on a casing of an operation switch is tiltably operated, the click module comprising:

• a click face on which a crest portion or a valley portion is formed;
• a click element which slides on the click face;
• and a resilient member which biases the click element to a click face side,
• wherein the click module is detachably mounted on the casing,
• wherein the click element and the click face slide relative to each other in an interlocking manner with a tilting operation of the operation knob,
• wherein the click module further comprises:
• a holding member detachably mounted on the casing, in which a hole portion that allows the insertion of the resilient member on a deep side thereof and the insertion of the click element on an opening side thereof is formed;
• and
• an inclination member mounted on a periphery of the holding member, on which the click face is formed such that the click face faces the hole portion in an opposed manner, and
• wherein the inclination member makes the click face slide relative to the click element by inclining in an interlocking manner with the operation knob.
