There is provided a semispherical shoe which is formed into a substantially semispherical shape by a convex semispherical surface 2 and a flat end surface 3, the semispherical surface having a slidably contacting surface 6 that is in slidable contact with a semispherical concave portion and non slidably contacting surfaces 7 and 8 that are not in slidable contact with the concave portion. When the semispherical shoe is manufactured, first, after a semispherical material having a semispherical surface following the concave portion has been formed, the surface of the portion that is to be the slidably contacting surface on the semispherical surface is quenched to expand the quenched portion from the original surface of the semispherical surface, whereby the sliding surface is formed on the surface of the expanded portion, and the other portions are made the non slidably contacting portions.
