摘要： The present invention is directed to split bodies for assembling a synthetic resin blower fan by a hollow article molding process. The split bodies have a first split body which includes a circular base portion and vanes extending radially and a second split body assembled on top of said first split body and is in a doughnut-shaped cap with an air inlet at the center thereof. Air channels are formed between adjacent pair of the vanes. The second split body includes a plurality of grooves which are formed on an inner surface opposite from the first split body in an assembled state. Each of the grooves extends radially along an edge of a corresponding vane and is adapted to be closed by the edge so as to define a flow path for allowing a molten synthetic resin to pass therethrough. The second split body further includes an injection hole which is in fluid communication with an upstream end of the flow path with respect to the flow direction of the molten synthetic resin to be injected so as to allow the molten synthetic resin to be injected into the flow path therethrough.

摘要： A vibration-isolating member is formed of an elastic material, and has a mounting hole at the center thereof, a large diameter section at an end of the mounting hole, a groove at the periphery of the large diameter section, and a flange. One of a vibration-source-side member and a vibration-receiving member is fitted into each of the large diameter section and the groove. An end opposite from the large diameter section is secured to one of the vibration-receiving member and the vibration-source-side member by a mounting member. Since the inside diameter of the large diameter section is larger than any other part of the mounting hole, either of the vibration-source-side member or the vibration-receiving member and the mounting member can be received. The flange prevents the vibration-isolating member from disengaging from one of the vibration-source-side member and the vibration-receiving member.

摘要： A power blower includes a frame, and a blower mounted on the frame. An air intake port of the blower faces the frame. There is provided an air intake space between the blower and the frame. A debris-catching cover is constructed between the frame side and the blower side in a state in which it is mounted on both the frame and blower sides. The debris-catching cover inhibits debris from being sucked from the air intake space into the air intake port.
