A slider is incorporated in a connector. A guide is designed to guide movement of the slider along a predetermined plane. An elastic terminal or contact extends to the free tip end from the stationary end. An inclined surface is defined on the slider so as to receive the elastic terminal. The inclined surface extends along an imaginary plane intersecting an imaginary reference plane including the predetermined plane by a predetermined inclination angle. The movement of the slider enables displacement of the contact position between the inclined surface and the elastic terminal in the connector. The inclined surface generates a driving force directed to the elastic terminal in response to the movement of the slider. The elastic terminal is thus caused to deform. This deformation can be utilized to control the contact between the elastic terminal and a connective member to be connected.
