PROBLEM TO BE SOLVED: To provide an electric unit which makes large sounds less likely to occur when a movable element drives, and to provide a small electric device including the electric unit.SOLUTION: An electric unit 60 includes: a linear motor; a motor case housing the linear motor; a movable element 64 connected with the linear motor and configured to reciprocate relative to the motor case; and a seal member 70 sealing a gap between the movable element 64 and an opening of the motor case. The seal member 70 includes: a contact part 71 which contacts with the movable element 64; and a recessed part 72 which is formed around the contact part 71, opens toward the outside of the motor case, and deforms in conjunction with driving of the movable element 64.SELECTED DRAWING: Figure 3 【課題】可動子が駆動しているときに大きな音が発生しにくい電動ユニットおよびこれを備える小型電気機器を提供する。【解決手段】電動ユニット６０はリニアモーターと、リニアモーターを収容するモーターケースと、リニアモーターと連結され、モーターケースに対して往復駆動する可動子６４と、可動子６４とモーターケースの開口との隙間をシールするシール部材７０とを備える。シール部材７０は、可動子６４と接触する接触部７１、および、接触部７１の周囲に形成され、モーターケースの外部に向けて開き、可動子６４の駆動にともない変形する凹部７２を備える。【選択図】図３
