Provided is a pressure coupling connector which can decrease the number of components for coping with various electric wire diameters, prevent problems due to difference in product kind, and reduce the stock. The pressure coupling connector includes a wire holding block for holding electric wires and a contact block for holding a connection terminal to which the electric wire is coupled with pressure by inserting the wire holding block into the contact block. The connection terminal of the contact block includes a U-shaped blade rising toward an opening surface into which the wire holding block is inserted. The wire holding block includes a wire holding portion in which a holding hole for transmitting the electric wire from the rear side thereof and holding the electric wire is formed and a reception groove for receiving the U-shaped blade of the connection terminal. The U-shaped blade of the connection terminal includes a core pressing blade having a step-shaped slit with two different widths in the vertical direction and a wire holding blade having a step-shaped slit with two different widths in the vertical direction, sequentially from the inside in an electric wire insertion direction. Adapting to the outer shape of an electric wire, the electric wire can be held with a wire holding slit (upper step portion)or a wire holding slit (lower step portion)

A dry shaver is capable of being depressed equally at different positions but with differing contact pressures between outer and inner cutters. The shaver has a housing having a motor and inner and outer cutters at its upper end. The inner cutter is driven by the motor to move in shearing engagement with the outer cutter for shaving hairs. The inner cutter is urged upwardly by a bias spring to develop a contact pressure against the outer cutter. The outer cutter is carried by a cutter holder movably supported to a head frame mounted on top of the housing. The shaver has a height adjust mechanism for adjusting the height of the head frame relative to the housing between a high position and a low position while compressing the spring differently to vary the contact pressure, and for allowing the cutter holder to be depressed relative to the head frame from each of the height and low positions.
