The present invention relates to an input device capable of detecting an acceleration, in which a detecting section constituted by a combination of a weight, a coiled spring, and detecting means is supported by a support. The support is fixed to a tip end within a case of the input device. By applying a force having a predetermined or higher acceleration in W direction with a grip part of the input device as fulcrum, thereby causing the input device to rotate, the weight is moved by the resulting centrifugal force in a direction in which the coiled spring is compressed, and an electric signal outputted from the detecting means varies according to the amount of the movement of the weight. By detecting this variation it is possible to detect an acceleration upon rotation of the input device.
