Abstract: A multi-function electronic appliance (1) includes an appliance body (2), an operation display unit (3), rollers (14) and spring pieces (20). The appliance body (2) is provided with a plurality of upright walls (10c). In the upright wall (10c), a guide groove (16) is formed. A through-hole (17) is opened in the guide groove (16). The operation display unit (3) is moves between the position where it covers the front face of the appliance body (2) and the position where it partially opens at least a part of the front face. The roller (14) is provided so as to be rotatable at the upper end of the operation display unit (3) and engaged with the guide groove (16). The spring piece (20) includes an attaching segment (21) attached to the appliance body (21) and an elastic deforming segment (22). The elastic deforming segment (22) advances into the guide groove (16) through the through-hole (17) and urges the roller (14) toward the front face when the operation display unit (3) covers the front face.

Abstract: A car stereo (1) as electrical equipment includes a main body (2) and a cooling device (4). The main body (2) includes a chassis (10). The chassis (10) receives the cooling device (4). The cooling device (4) includes a heat sink (20), an electric fan (21), and a cover (22). The heat sink (20) is thermally connected to a power IC (6) as a heating element and the like. The heat sink (20) is vertically provided on a bottom chassis (11) of the chassis (10). A cover (22) is attached to the heat sink (20) and the bottom chassis (11). The heat sink (20), the cover (22), and the bottom chassis (11) form an inner closed flow space (100). The electric fan (21) moves a gas into the flow space (100).
