To enhance the effect of decelerating high-speed water, such as slurry, intruding from the outside in a radial direction into a clearance in a shaft direction, until the water reaches an outer diameter side seal.SOLUTION: The first wall surface 3A of a lower side case is an outer peripheral surface facing a shaft direction clearance C. The second wall surface 3B of the lower side case is an annular surface extending from an upper end of the first wall surface 3A of the lower side case to the radial direction outside RO. The third wall surface 3C of the lower side case is an outer peripheral surface extending from an end E of the radial direction outside RO of the second wall surface 3B of the lower side case to an upper side. The first wall surface 2A of an upper side case is an inner peripheral surface facing an upper part of the first wall surface 3A of the lower side case. The second wall surface 2B of the upper side case is an annular surface extending from an upper end of the first wall surface 2A of the upper side case to the radial direction inside RI. The third wall surface 2C of the upper side case is an inner peripheral surface which extends from an end F of the radial direction inside RI of the second wall surface 2B of the upper side case to the upper side, and which faces the third wall surface 3C of the lower side case.SELECTED DRAWING: Figure 3

    【課題】軸方向隙間に径方向外方から浸入した泥水等の高速の水を、外径側シールに到達するまでに減速させる効果を高める。【解決手段】下側ケース第1壁面3Aは、軸方向隙間Cに対面する外周面である。下側ケース第2壁面3Bは、下側ケース第1壁面3Aの上端部から径方向外方ROへ延びる円環状面である。下側ケース第3壁面3Cは、下側ケース第2壁面3Bの径方向外方ROの端部Eから上方へ延びる外周面である。上側ケース第1壁面2Aは、下側ケース第1壁面3Aの上部に対面する内周面である。上側ケース第2壁面2Bは、上側ケース第1壁面2Aの上端部から径方向内方RIへ延びる円環状面である。上側ケース第3壁面2Cは、上側ケース第2壁面2Bの径方向内方RIの端部Fから上方へ延びる、下側ケース第3壁面3Cに対面する内周面である。【選択図】図3
