Abstract: A motor having a rotor connected to an input shaft and a stator fixed by a fixing jig during assembly to a case includes: a stator convex part that extends radially outward from an outer circumference of the stator and positions the stator with respect to the case; and a case convex part that extends radially inward from an inner circumference of the case and is arranged so as to overlap with the stator convex part in a circumferential direction. A relief part is provided between the stator convex part and the case convex part, the relief part being arranged such that the stator convex part can be rotated along the circumferential direction with respect to the case during assembly.

Abstract: A light adjusting sheet for a planar lighting device includes a plurality of convex and concave ridges or regions arranged alternately and approximately parallel to each other on one surface. Each of the convex regions and concave regions are formed by two flat surfaces. The ridges may have a cross section of a sine curve. Another light adjusting sheet consists of a plurality of single sheets each having the above configuration, stacked together. A planar lighting device includes the light adjusting sheet of the above configuration, wherein peak lines of the convex ridges and bottom lines of the concave ridges are arranged to make a predetermined angle with an axis of a linear light source. The liquid crystal display includes a liquid crystal display element placed on front of the planar lighting device of the above configuration.

Abstract: A light adjusting sheet for a planar lighting device includes a plurality of convex and concave streaks arranged alternately and approximately parallel to each other on one surface. The streaks may have a cross section of a sine curve. Another light adjusting sheet consists of a plurality of single sheets each having the above configulation, stacked together. A planar lighting device includes the light adjusting sheet of the above configulation, wherein peak lines of the convex streaks and bottom lines of the concave streaks are arranged to make a predetermined angle with an axis of a linear light source. The liquid crystal display includes a liquid crystal display element placed on front of the planar lighting device of the above configulation.
