    • PROBLEM TO BE SOLVED: To provide a tilt hinge device capable of being miniaturized in a direction orthogonal to a rotary shaft center, formed with a high degree of accuracy in a manner such as to obtain a rotational torque with homogeneity and stability, and produced efficiently. SOLUTION: In the tilt hinge device provided with a rotary shaft body 15 and a bearing fitting unit 20 having a bearing part 22 for bearing the shaft body 15, the bearing part 22 of the fitting unit 20 is provided with the first bearing piece 30 provided with the first half-split curl part 32 fitted with an arc-shaped cross section inner surface 32a contacting the outer periphery surface 16a of a rotary shaft part 16, the second bearing piece 40 provided with the second half-split curl part 42 fitted with an arc-shaped cross section inner surface 42a contacting the surface 16a of the shaft part 16, and a sandwich-holding means 24 for holding the shaft part 16 in such a condition as to sandwich the shaft part 16 between the bearing pieces 30, and 40.

    • PROBLEM TO BE SOLVED: To form a grated frame of high strength and uniform load bearing force without being influenced by the thickness and length dispersion of wood in slope frame structure and a work execution method in a wooden slope frame construction method for preventing the fall and erosion of the ground surface. SOLUTION: This wooden slope frame is formed of a large number of columnar members inclined to one side and the other side orthogonal to each other. One end of each columnar member is butt-connected to the side face of the columnar member in the orthogonal direction, and the side face of the other end is splice-connected to the end part side face of the columnar member in the same direction. The butt-connected position is the mutual splice-connected part of two columnar members pointing in the same direction. The splice- connected part of two columnar members pointing in the same direction is fastened by two screw rods piercing both columnar members, and the base ends of the screw rods are fixed to the butt-connected end parts of the columnar members in the orthogonal direction to two columnar members.

    • PROBLEM TO BE SOLVED: To enable an automobile driver to clearly visually recognize signal light even in the case where a signal is directly irradiated with the morning sunshine or evening sunshine by arranging a light-transmissible reflection body which reflects the sunshine obliquely and transmits the signal light forward to the front of a housing so that its reflecting surface is slanted to the signal. SOLUTION: In front of a lens 5, the light-transmissible reflection body 7 which has a smooth top surface and superior reflectivity is arranged bending forward at about 20 deg. to the perpendicular. When the sunshine A impinges on the light-transmissive reflection body 7 at an incidence angle of 10 deg. to a horizontal road surface, reflected light (a) reflected by the light-transmissive reflection body 7 is reflected on the road surface right before the signal 1 at about 30 deg. to the perpendicular. Therefore, lights (a), (b), and (c) of the reflected sunshine reflected on the road surface at angles of about
