    • A linear motion guide unit, having force-information detecting means and enabling reductions in size and manufacturing cost, is provided with a casing having a mounting portion combined with two wings which have rolling-contact faces facing a track rail and return holes interconnecting with the rolling-contact faces and incorporate rollers rolling through the rolling-contact faces and the return holes. The rollers move the casing along the track rail while rolling between the rolling-contact faces and the track rail. A load acts on the casing and a force acts on the wings in the direction of moving them farther away from each other. Bulge portions are created on the outer side-faces of the wings by the action of the force, in which tensile-strain detection sensors are provided. Compressive-strain detection sensors are provided in depression portions created next to the bulge portion closer to the mounting portion when the bulge portions are created.
    • 具有力信息检测装置并且能够减小尺寸和制造成本的直线运动引导单元设置有壳体,该壳体具有与具有面向轨道轨道的滚动接触面的两个翼部结合的安装部分和与 滚动接触面并且包括滚动通过滚动接触面和返回孔的滚子。 滚子在滚动接触面和轨道轨道之间滚动时沿着导轨移动壳体。 负载作用在壳体上,并且力沿着将它们彼此远离的方向作用在翼上。 通过施加拉伸应变检测传感器的力的作用在翼的外侧面上产生膨胀部分。 当产生凸起部分时,压缩应变检测传感器设置在靠近安装部分的凸起部分旁边形成的凹陷部分中。

    • An encoder-equipped sealing device, that is, a sealing device that has an encoder incorporated therein is disclosed, which comprises a combination of seal elements, each of which includes an annular metal core having a substantially L-shaped cross section and including a cylindrical portion and a flange portion provided on one end of the cylindrical portion and extending in a direction perpendicular to a direction in which the cylindrical portion extends. One seal element, of the two seal elements, and the other seal element are combined such that a space defined by the cylindrical portion and flange portion of the one seal element, and a space defined by the cylindrical portion and flange portion of the other seal element, face opposite each other, wherein the one seal element further includes an elastic seal portion provided on the flange portion and arranged in the space defined by the cylindrical portion and flange portion, and the other seal element further includes a magnet-based encoder provided on the flange portion. The one seal element further includes a projecting portion on an end of the cylindrical portion on a side on which the flange portion is located and extending beyond a side of the flange portion opposite a side on which the seal portion is located and in a direction in which the cylindrical portion extends.
