摘要：
A slide electricity structure according to the present invention uses grease for electrical contacts wherein contact resistance does not gradually increase even when exposed to sliding and lifetime is long, and has a silver-plated spring contact that contacts or separates by way of sliding and grease for electrical contacts that has been applied to the spring contact and contains perfluoropolyether oil having an average molecular weight between 2600 and 12500 as a base oil and PTFE having a primary particle diameter of 1 μm or less as a thickener.
