An optical information recording apparatus includes a first optical system that radiates an information beam that carries information onto a recording medium; a second optical system that radiates reference beams onto the recording medium; a radiation position specifying unit that specifies a plurality of recording spots positioned within a radiation range of the reference beams; and an incident angle obtaining unit that specifies an incident angle of the reference beams that is used for recording an i'th interference fringe into a second recording spot adjacent to a first recording spot, as a value obtained by adding a product of 1/(1+m) and an absolute value of a difference between an incident angle of a first reference beam used for recording an i'th interference fringe into the first recording spot and an incident angle of a second reference beam used for recording an (i+1)'th interference fringe into the first recording spot.

An electrical junction box is provided to reduce looseness of a cover. The electrical junction box includes a box body and the cover to be slidably mounted on a lateral side of the box body from above. The cover has a front wall and a pair of left and right sidewalls connected to both left and right ends of the front wall to overlap with left and right connecting walls of the box body, providing a U-shaped cross section. The electrical junction box further includes first slide guides provided on both of the cover and the box body and second slide guides provided on both of the cover and the box body. The second slide guides are positioned in areas where the left and right sidewalls of the cover overlapping with the left and right connecting walls of the box body. Further, the second slide guides are closer to the front wall of the cover being mounted to the box body than the first slide guides.

An electrical junction box includes an accommodation box having an accommodation box body having an accommodation space penetrating trough the accommodation box body up and down and an electrical component mounting block inserted into the accommodation space from either upside thereof or the underside and fixed in the accommodation space. The electrical junction box fiber includes a first locking mechanism arranged between an inner wall of the accommodation box body and an outer wall of a block body to lock up the electrical component mounting block inserted into the accommodation space from its upside and a second locking mechanism arranged between the inner wall of the accommodation box body and the outer wall of the block body to lock up the electrical component mounting block inserted into the accommodation space from the underside.

Provided is a structure for housing an electrical junction box in a housing box by inserting the electrical junction box into the housing box from above and also for fixing the electrical junction box to the housing box so as to prevent slipping-off thereof by engagement between engagement parts provided on external side surfaces of the electrical junction box and engagement parts provided on internal side surfaces of the housing box, both of which face each other in parallel with an insertion direction in insertion of the electrical junction box. Moreover, groove-like depressions extended along the insertion direction into the housing box are provided in the external side surfaces of the electrical junction box, and engagement convex parts are provided in the depressions. Furthermore, engagement projections engaged with the engagement convex parts are provided on the internal side surfaces of the housing box. As depressions behind the engagement convex parts in the insertion direction, die-releasing holes for injection molding for forming locking parts of the electrical junction box are used.

A wire harness leading-out opening is provided at a junction between an electric connection box and a bottom surface cover which constitute an electric connection box. A cylindrical wire harness leading-out guide is provided on the periphery of the wire harness leading-out opening, and is formed in a way that the both circumferential ends of a half-cylindrical body formed on the electric connection box and a half-cylindrical body formed on the bottom surface cover are coupled to each other. In the inner circumference of a circumferential junction between the peripheral walls of the two half-cylindrical bodies, a concave portion is provided to accommodate a loose portion of an armoring member wrapped around the outer circumference of the wire harness.

摘要:
The interior of a case body is partitioned into two chambers by a partition wall, and the two chambers communicate with each other via a communication passage defined by a notch formed in the partition wall. First and second covers are attached to the case body, and cover open sides of the two chambers, respectively. The first and second covers have lap portions, respectively, which cover an open end of the communication passage in overlapping relation to each other.
