Light that enters from an incident light surface of a light guide plate includes not only light which is guided toward the forward direction in front but also light whose optical path is modified by optical elements while progressing through the inside of the light guide plate, and thus wasteful emission from an emitting surface is inhibited. Lights are guided in a longitudinal direction of the optical elements. Light is diffused in the course over which the lights are guided and the region to which they are guided. The lights are guided by the optical elements in the longitudinal direction of the optical elements, and thereby light diffusivity is exhibited in the region in which the optical elements are provided while controlling the directivity of the light.

A ball bearing (rolling bearing) containing lubricant sealed therein is provided between a shaft and a sleeve. A labyrinth seal (seal gap) is provided at an end portion of the shaft or the sleeve in the axial direction. A permanent magnet is disposed such that a magnetic pole is located in proximity to the labyrinth seal. A magnetic seal effect that utilizes diamagnetism acting on evaporating oil is provided at the labyrinth seal.


There is provided an ultraviolet curable resin composition for a self-lubricating liner. The composition includes a first (meth)acrylate compound having an isocyanuric acid ring represented by the following formula (1); a second (meth)acrylate compound different from the first (meth)acrylate compound; a first polytetrafluoroethylene resin with an average particle size in the range of 75 m to 180 m; and a second polytetrafluoroethylene resin with an average particle size in the range of 1 m to 15 m, wherein the total amount of the first polytetrafluoroethylene resin and the second polytetrafluoroethylene resin is in the range of 30% by weight to 50% by weight with respect to the entire amount of the ultraviolet curable resin composition; and the second polytetrafluoroethylene resin is contained in an amount of 20% by weight to 75% by weight with respect to the total amount of the first and second polytetrafluoroethylene resins.
