A fan type noxious insect control apparatus is disclosed which is desirably used carried on a user's body part and excels in noxious insect control performance. To this end, the apparatus is so configured that air is drawn through an inlet port () by driving of an axial flow fan () and passed through a chemical carrier () carrying a noxious insect control active ingredient to form the air containing such active ingredient, the air being run out through an outlet port () to diffuse the active ingredient into the ambient atmosphere and further that the inlet port () at an upstream of the fan () is open facing axially thereof, the outlet port () at a downstream of the fan () is open facing radially thereof, and there are provided an annular wall () surrounding the fan () and an air flow passage () communicating between a delivery section of the fan () and the outlet port () to convert air flowing out of the axial flow fan () axially thereof to air flowing radially thereof.

Fan type noxious insect control apparatus

The invention relates to a bearing device for a motor comprising a rotor frame with a field magnet provided on an inner periphery thereof, a shaft coupled to the rotor frame, an oilless bearing for rotatably supporting the shaft, a stator fixedly accommodating the oilless bearing, and a stator fixed to an outer peripheral portion of the stator boss. The bearing device comprises an annular oil seal washer made of a viscoelastic member with an least an adhesive layer provided on a surface thereof, and a substantially disk shaped resin cap. The oil seal washer is sandwiched between an end surface of the stator boss and the resin cap fixed on an inner peripheral surface of a stator boss supporting portion.

Bearing device for motor

An axial fan motor comprising a cylindrical bearing boss having therein a bearing mechanism for supporting a rotational shaft of the axial fan motor and a stator core coupled to the cylindrical bearing boss is disclosed. The bearing boss is, at its one end portion, coupled integrally to an insulator so that said stator core is sandwiched between the insulator and another insulator so as to insulating the stator core. A stator-holding section is defined in a housing of the axial fan motor and the stator-holding section has a cylindrical bearing boss receiving portion whose axis is substantially coincident with the axis of the rotational shaft of the axial fan motor. The bearing boss receiving portion includes upper and lower engaging portions which are engaged with the bearing boss when the bearing boss is inserted into the bearing boss receiving portion so that the upper engaging portion carries the stator core through the insulator and the lower engaging portion engages with the other end portion of the bearing boss.
