Abstract: A force sensor includes a shaft to which a magnet is fixed, and a case which can reciprocate with respect to the shaft and to which a Hall IC element is fixed. The Hall IC element outputs an output voltage which changes in accordance with relative displacement between the Hall IC element and the magnet. A main spring is interposed between the shaft and the case and elastically deforms in accordance with force produced between the shaft and the case in the reciprocating direction. A sub spring is provided in order to impart a preload such that when the amount of elastic deformation of the main spring is substantially zero, no axial clearance is formed between a flange portion of the shaft and one end portion of the main spring, and no axial clearance is formed between the case and the other end of the main spring.
