Disclosed is a portable terminal in which a casing that pivots about a single axis of rotation is prevented from opening, while pivoting of the casing about the axis of rotation in the direction perpendicular to the single axis of rotation is restricted. A bearing member (50) functions as a movement control section for controlling the position of a moving member (48) by pivoting, with respect to a linking part (4), about an axis (a) (first axis of rotation) through a predetermined angle in the opposite direction to the direction of arrow A. The bearing member (50) controls the pivot movement of an upper casing (2) with respect to a lower casing (3) in the direction of arrow B about an axis (b). A side surface (112D) of a large diameter section (112) of the bearing member (50) abuts a first protrusion (301) which is formed in the lower casing (3) and protrudes into the casing.
