Abstract: Lock portions 4 are provided more inside than outermost wall surfaces 5a, 6a of a cassette relay block 1, and the cassette relay block 1 is inserted into space surrounded by peripheral walls 16 to 19 on an attaching side, and fixed by the lock portions 4 and locked portions 10 located on the peripheral wall side. The peripheral walls 16 to 19 on the attaching side are formed as a cassette frame 2. The cassette frame is used in common for the cassette relay block 1 or other cassette electric parts mounting blocks. The plural cassette frames are coupled to each other by lock members 54, and coupled to a connection box body by locked members thereby to constitute an electric connection box.

Abstract: An electric distribution box, includes a box body for being placed in a vehicle room; a mounting portion which is provided on the box body for being fixed to a vehicle body, and a rupture induction portion which is provided at a box body side of the mounting portion for inducing the rupture of the mounting portion by an impact upon collision of a vehicle so as to separate the box body from the vehicle body. The mounting portion is divided into two virtual sections by a line passing through a center of an insertion hole of the mounting portion, the longitudinal axis being substantially parallel to an advance direction of the vehicle. The rupture induction portion is provided at one of the two virtual sections which is disposed in a direction away from a direction of laterally-inclining of the box body upon collision of the vehicle.

Abstract: A chromium-free agent for treating metallic surface comprising the following (i)-(iv): (i) at least one of (A) a mixture of an aluminum salt and an inorganic oxide particle and (B) an aluminum-containing inorganic oxide particle comprising aluminum, oxygen and at least one element other than these two (ii) a salt of a metal other than aluminum (iii) a phosphorus compound (iv) a resin and/or a precursor thereof provided that when (i) is a mixture of an aluminum salt and an inorganic oxide particle, the equivalent ratio of phosphorus/aluminum is not less than 0.1. The agent for treating metallic surface is applied to the surface of a metal material such as steel plate, plated steel plate, alloy-plated steel plate, alloy plate, silicon steel plate, stainless steel plate, shape steel, pipe, wire material and the like, and dried to form a film superior in corrosion resistance, adhesion to a metal material and adhesion to a paint.

Abstract: A heat-radiation structure of an electronic-unit box in which an air layer is formed between a primary peripheral wall of the electronic-unit box and a secondary peripheral wall located inside the primary peripheral wall, and an electronic unit is received inside the secondary peripheral wall, an air intake and an air outlet are provided in a box body so as to communicate with the air layer, and air interrupting walls are provided in a shorter peripheral-distance-side flow path of the air layer between the air intake and the air outlet so that cooling air passes through a longer peripheral-distance-side flow path of the air layer from the air intake to the air outlet. Preferably, an electric fan is provided at the air outlet.

Abstract: A waterproof casing including a casing body which has a substantial box-shape and a lid which openably closes an open portion of the casing body. The casing body end the lid include respective first peripheral walls butted against each other to thereby prevent the intrusion of water into a receiving space for electrical parts, and also include respective second peripheral walls which are spaced outwardly from the first peripheral walls to form a space around the first peripheral walls, and are butted against each other, so that each of the joint portion between the first peripheral walls and the joint portion between the second peripheral walls forms a waterproof structure which limits the intrusion of water. The two joint portions are offset from each other in a vertical direction, and drain holes are formed through a bottom portion of the second peripheral wall of the casing body so as to reduce the pressure of a high-pressure water stream within the space and also to discharge the water from the space.
