なお、塗布用円板12は、図5および図6に示すように、正逆回転のいずれの回転方向においても軸方向の長さが長い塗布領域Aに対して良好に液状物を均一に塗布することができるように形成してもよい。 The coating for the disc 12, as shown in FIGS. 5 and 6, good uniform application of the liquid material against the forward and reverse rotation in either axial direction in the rotational direction of the length is longer application region A it may be formed so that it can be. 具体的には図5および図6に示すように、中心側の充填溝13から外側に径方向外側に向けて高さが高くなるテーパ面28を形成し、更に周方向を6等分する位置にそれぞれ正逆回転方向に対称形状の椀の一部を形成する凹部からなる液状物誘導面14を径方向外側に向けて深さが深くなるように形成し、各液状物誘導面14の塗布用円板12の外周面との交点を飛散端縁15としたものである。 More specifically, as shown in FIGS. 5 and 6, a tapered surface 28 which gradually increasing in height toward the radially outward from the center to the outside of the filling groove 13, further a circumferential direction 6 equally divided positions the formed such that the depth becomes deeper toward the liquid material guiding surface 14 formed of the recess which forms part of the bowl of the forward and reverse rotation directions symmetrically radially outwardly respectively, application of the liquid material guide surface 14 the intersection of the outer peripheral surface of the use the disc 12 is obtained by the scattered edge 15. この飛散端縁15の最低位置と最高位置との高低差を前記塗布領域Aの高さと同一とすることにより、塗布用円板12の正逆回転のいずれの回転方向においても軸方向の長さが長い塗布領域Aに対して良好に液状物を均一に塗布することができる。 By the height difference between the lowest position and the highest position of the scattered edge 15 the height of the same said coating region A, positive vice axial length in either direction of rotation of the rotation of the application for the disc 12 it can be uniformly applied satisfactorily liquid material for long coating region a.

また、前記実施形態においては、オイルシールに潤滑剤を塗布する場合について説明したが、塗布媒体としての液状物としては潤滑剤に限らずに塗料、染料等を含むものであり、塗布対象としてはオイルシールのシールリップに限らずに装飾用筒体等を含む環状製品の環状の内周面を含むものである。 Further, in the above embodiment has described the case of applying the lubricant to the oil seal, the liquid material as a coating medium is intended to include paint not limited to lubricants, dyes and the like, as the coating object it is intended to include the inner peripheral surface of the annular ring products including decorative cylindrical body or the like is not limited to the sealing lip of the oil seal.

また、本発明は前記各実施形態に限定されるものではなく、必要に応じて種々変更することが可能である。 Further, the present invention is not limited to the above embodiments, it can be variously changed as necessary.
