Abstract: An LED lighting unit having a circuit board on which a plurality of LED elements are mounted and a light transmitting housing in which the circuit board is accommodated. The LED lighting unit includes a light screen cover formed so as to cover an outer surface of the light transmitting housing and having light output opening parts formed on walls of the light screen cover respectively opposed to the plurality of LED elements and a light screen member which screens in an inner part of walls of the transmitting housing lights guided in the walls of the transmitting housing so that the lights emitted respectively from the plurality of LED elements are guided in the walls of the transmitting housing and do not interfere with each other.

Abstract: When the edge surfaces of the circuit board side cut-out part and the light screen member side cut-out part which are respectively orthogonal to the cutting directions are allowed to abut on each other so as to attach the light screen member to the circuit board, the light screen member is attached to the circuit board so that both the end surfaces of the light screen member opposed to each other in the cutting direction of the light screen member side cut-out part are arranged more inside than both the end faces of the circuit board opposed to each other in the cutting direction of the circuit board side cut-out part.

Abstract: In a sealing structure, an elongated projecting portion is formed on an outer circumferential surface of a holder in a position forward in an inserting direction of the holder than an annular packing, the elongated projecting portion projects than the annular packing in a radial direction of the holder, a recess portion is formed on an inner circumferential surface of an opening portion of the holder so that the elongated projecting portion is inserted therein, and the recess portion has such a depth that the annular packing is pressed by the inner circumferential surface of the opening portion in a state where the elongated projecting portion is inserted into the recess portion.

Abstract: An object of the invention is to provide an electric wire holder capable of facilitating an end treatment of a wiring harness to reduce the fabrication cost of the wiring harness and of increasing the reliability in the insulation displacement connection at the end portion of the wiring harness. In an electric wire holder 1 including a holder main body 5 which holds a plurality of electric wires 3 in parallel with an electric wire alignment portion 11 and a holder cover 6 which sandwiches portions 3a of the electric wires 3, which are led out from the holder main body 5 together with the holder main body 5, the electric wire alignment portion 11 is formed with a plurality of leading end insulation holes 14 through which leading end portions 3b of the electric wires 3 are inserted so that the electric wires 3 are positioned in parallel and an insulation displacement blade insertion hole 15 through which an insulation displacement blade 31 is inserted from the outside.
