摘要： PURPOSE:To simplify the sealing between a housing and an end bracket and that to obtain a motor fan of good radiating effect by interposing an elastic member to the mating face between the housing and the end bracket. CONSTITUTION:In a cooling electric fan of a heat exchanger, etc. of an automobile, an elastic member 10 formed by rubber plate, etc. is interposed to the mating face between the end portion 6a of a housing 6 and the end portion 8a of an end bracket 8. The elastic member 10 is fixed to the mating face by fastening the clearance between both end portions 6a and 8a with rivets, etc. compressing the elastic member 10. In this work an adhesive is coated to a surface of the elastic member 10 so that the elastic member 10 will not be left out of the mating face. Thus, without reducing the surface area of housing and end bracket, the mating face can be sealed. Consequently, the sealing can be performed easily and a motor fan of good radiating effect obtained.

摘要： PURPOSE:To prevent noise from being emitted outside by making peripheral part of a blower case of a blower motor of double structure consisting of a housing and a cylindrical body with a certain gap between the two. CONSTITUTION:A cylindrical wall 13d is arranged on the peripheries of a housing 13b and an end bracket 13a of a blower motor 13 of a blower 4 of a motor vehicle to form a double structure. Since a sound absorbing material 17 can be glued in a gap formed with the said double structure, outside emission of noise can be reduced, eliminating the need for attaching a motor cover.

摘要： PURPOSE:To check water spread along a wall surface as well as to make rainwater preventable from penetrating into a driving motor, by installing an air intake for cooling a motor in a heat exchanger case, being joined with a slip stream of a blower case or a duct. CONSTITUTION:A cooling water intake 60 of a cooling unit cast 50 is installed at the more downstream side of a wind than a blower case discharge surface 2. Therefore, an amount of rainwater penetrated inside a blower case 1 is spread wide at the cooling unit side, so that a possibility of the rainwater being entered inside a motor from the air intake installed in the blower side is brought to nothing at all. In addition, it is effective that a waterdrop flowing along a blower case wall surface is absorbed, owing to a groove 41 formable in a joining part between the cooling unit case and the blower case discharge surface or wind-leak preventing packing 40.

摘要： PURPOSE:To provide sound absorption effect over a wide frequency region by arranging plural sound absorption members each having different sound absorption frequency characteristics on an internal wall surface of an intake duct being a passage for a wind and on a door surface in an automatic car fan. CONSTITUTION:A sound absorption member 9 is sticked to an internal wall surface 8 of an intake duct 2 being a wind passage. A fresh air leakage preventing seal member 11 is sticked to a surface of a door 1 facing the fresh air intake 6 side. In addition, a sound absorption member 13 having a sound absorption frequency characteristic different from that of the sound absorption member 9 is sticked to a surface 12 facing the internal air intake 7 side. In an internal air absorption mode where the door 1 is located on the fresh air intake 6 side, a wind is absorbed from the internal air intake 7 of the duct 2 and allowed to enter a scroll 3. Hereupon, the absorbed wind strikes the sound absorption members 9, 13 sticked to the duct 2 internal wall surface and the door surface, whereby noise energy is reduced by the respective sound absorption frequency characteristics. Thus, sound absorption effect can be obtained over a wide frequency region.

摘要： PURPOSE:To improve the efficiency of assembly operation by inserting a long screw into a hole provide in the flange and the cooling body of a transistor; and by fixing a lead wire with a nut attached to the end of the long screw. CONSTITUTION:2 Pieces of long screws 302 are inserted into holes provided in the flange 51 and the cooling bodies 40 and 41 of the transistor 5. The claw 710 of the lead wire 71 is held in the place of the long screw with the nut 301 by driving the nut from the end of the screw 302. By so doing, the transistor 5 and the lead wire 71 can be conveyed on the production line as an integrated part, and the efficiency of assembly operation is improved.

摘要： PURPOSE:To shorten the shorted period of brushes by arranging a coil piece of a coil which is shorted by a positive brush adjacent to a coil piece of a coil which is shorted by a negative brush and overlapping the shorted periods of both coils. CONSTITUTION:In the process where armature coils 3a to 3s are connected to commutator segments 2a to 2s, the opening angle thetax of a coil is selected to be e.g. 89 deg. so that one coil is placed over five pins of an armature-forming jig. Thus, coils which are shorted during the period a positive brush 8a and a negative brush 8b move from commutator pieces 2a to 2b and from 2f to 2g, respectively, are 4coils 3b,3k,3g, and 3p, and coil pieces 3p'' and 3b', 3k' and 3g'', and 3K'' and 3p' which form pairs, respectively, are adjacently arranged. In this constitution, the operlapping period of individual pairs during which the coil pieces are shorted becomes long, thereby the period during the shorted coil crosses the main magnetic flux can be decreased, and the occurence of an exciting force to a casing can be reducd.
