Input device

An input device comprising:

• an operation component that tilts in a first direction in response to a user operation;
• an expansion component that tilts in the first direction relative to the operation component, in conjunction with tilting of the operation component;
• a detected element to be detected that is supported by the expansion component;
• a detector that is disposed to face the detected element, and detects a tilting movement made by the operation component;
• a detent pin that provides a clicking sensation for an operation to tilt the operation component, and is supported by the expansion component in a retractable manner;
• and
• an energizing component that energizes the detent pin toward a detent surface to press a tip of the detent pin against the detent surface, wherein
• with respect to a tilt amount of the operation component, the expansion component increases a movement amount of the detected element and a movement amount of the tip of the detent pin in a direction parallel to the detent surface.
