<p>A structure for a tappet roller bearing has a support shaft (6), a circular tube-shaped inner diameter-side roller (12) fitted on the outer diameter surface of the support shaft (6), and a circular tube-shaped outer diameter-side roller (13) fitted on the outer diameter surface of the inner diameter-side roller (12). The structure satisfies the relationship of A > B, with A a radial gap between the outer diameter surface of the support shaft (6) and the inner diameter surface of the inner diameter-side roller (12), B a radial gap between the outer diameter surface of the inner diameter-side roller (12) and the inner diameter surface of the outer diameter-side roller (13).</p> |
