    摘要: A semi-contact guide apparatus includes a bed as a first member, a column as a second member, a plural number of oil-hold portions and an oil-supply device. The column is movably guided on the bed. A sliding surface is formed on the column. The plural number of oil-hold portions is formed on the sliding surface. Dimensions of the oil-hold portions are defined according to load distribution of the weight of the column. The oil-supply device supplies lubricant oil to the oil-hold portions. The amount of lubricant oil supplied to the oil-hold portion is defined according to each of dimensions of the oil-hold portions. Since the dimensions such as areas of the oil-hold portions and the amount of the lubricant oil supplied to the oil-hold portion are defined as above, inclination of the column on the bed is prevented, and the column can be smoothly moved on the bed.
