Example Embodiment
[0027] Example 1
[0028] Example 1 of the present invention passed Figure 1 to Figure 3 Be explained.
[0029] figure 1 This is a longitudinal sectional view of the cage 1 of this embodiment, figure 2 This is a cross-sectional view of the cage 1.
[0030] The cage 1 is formed of an annular main portion 1A, which is made of a composite material such as a cloth phenolic resin, and is formed in a manner that can be saturated with grease base oil.
[0031] 1a is a circular recessed hole for holding a ball, and this recessed hole 1a penetrates the said main part 1A in a radial direction, and the inner periphery is formed in a cylindrical shape.
[0032] 1b is a substantially rectangular recess, and the recess 1b is recessed in the respective intermediate portions of adjacent recessed holes 1a and 1a provided on the inner peripheral surface of the main portion 1A.
[0033] In addition, the depth of the recess 1b is set so as not to affect the strength of the main portion 1A, for example, a...

[0041] Example 2
[0042] Example 2 of the present invention passed Figure 4 Be explained.
[0043] Figure 4 This is a longitudinal sectional view of the cage 7 of this embodiment.
[0044] The holder 7 is formed by a ring-shaped main part 7A, which is made of a composite material such as cloth phenolic resin and formed in a widened form.
[0045] There are a plurality of cylindrical recessed holes 7a for holding the balls, which penetrate the main portion 7A in the radial direction.
[0046] 7b is a recess, and the recess 7b is formed in a convex shape having a thin protrusion 7bt on one side of a substantially square shape, and each recess 7b is at the center of the recess 7a connecting the inner peripheral surface of the main portion 7A Both sides of the center line of the part are symmetrically arranged so that each protrusion 7bt faces the center line. In addition, the depth of the recess 7b is, for example, about half of the thickness of the main portion 7A.

Example Embodiment
[0052] Example 3
[0053] Example 3 of the present invention passed Figure 5 with Image 6 Be explained.
[0054] Figure 5 This is a longitudinal sectional view of the cage 11 of this embodiment, Image 6 It is a cross-sectional view of the cage 11.
[0055] In the annular main portion 11A of the cage 11 of the present embodiment, the inner peripheral surface of the concave hole 11a for holding the balls is a spherical concave surface corresponding to the balls.
[0056] Here, the holder 11 is formed into two parts, and 11c is the joint part.
[0057] The shape of the recess 11b is the same as that of the recess 1b of the first embodiment described above.
[0058] By forming the concave hole 11a for holding the balls into a spherical shape in this way, the cage 11 can be prevented from vibrating in the radial direction.
[0059] This holder 11 is used in the same manner as the holder 1 of Embodiment 1 or Embodiment 2 described above.
[0060] In addition, the above-mentioned embodiment 1...
