摘要:
An electrolytic capacitor includes: a case including a case body, in which an electrolytic capacitor element is disposed in a sealed manner and filled up with an electrolytic solution, and a safety valve is mounted to the case body for jetting an evaporated gas of the electrolytic solution filling the electrolytic capacitor element; a cover member mounted to the case so as to cover the safety valve provided for the case; a first fixing unit mounted to the cover member so as to prevent the cover member from dismounting when the evaporated gas of the electrolytic solution is jetted outward; and a second fixing unit disposed in association with the first fixing unit and adopted to reinforce and assist a function of the first fixing unit to thereby prevent the cover member from being dismounted. An electric equipment includes a lighting circuit including circuit components, and an electrolytic capacitor of the structure mentioned above.
