Abstract
A lubricant supply source is disposed in the vicinity of a sliding or rotary portion of a machine element, and an electrical power source is intermittently driven by a controller, so as to intermittently supply lubricant from the lubricant supply source to the machine element. When required, a sensor for monitoring the operating state of the machine element, and/or a remote controller is used, so that the supply of lubricant is controlled on the basis of the signal of the sensor and/or by means of the remote controller. Consequently, lubricant can be supplied or supplemented to the machine element in accordance with necessity. Therefore, the machine element will be able to stably operate for a long time, even in relative inaccessible places which people cannot inadvertently access.
