Claims

[Scope of utility model registration request]

In a dynamic pressure type belly bearing in which either the shaft body or the bearing is supported through mutual sliding surfaces for linear movement in both forward and reverse directions or rotary linear movement, the sliding surface between the shaft body and the bearing is A lubricant reservoir is provided at both ends or in the middle of the bearing. A dynamic pressure bearing with a built-in lubricant, characterized in that the lubricant contained in the lubricant reservoir is brought into contact with the sliding surface of the shaft body, with or without a porous member interposed in the lubricant reservoir. Shaped bearing.
