  • Publication number: 20090103748
    Abstract: An object is to enhance workability in attachment in a sound generating apparatus that generates sound by vibrating a vibration plate with a vibrator while ensuring acoustic performance as good as that achieved by fastening with fine screw threads. Workability in attaching operation is improved while ensuring acoustic performance as good as that provided by fastening with fine screw threads, by providing first fixing means that brings engagement portions 31 and 41 into screw engagement with each other by rotation by a predetermined angle that can be attained by a user without taking his/her hand that holds a coupler 3 off it and second fixing means for fixing the coupler 3 to a bracket 4 so as to prevent the coupler 3 from rotating relative to said bracket 4 in a direction to loosen the engagement achieved by said first fixing means.

  • Patent number: 7481493
    Abstract: To promote bloodstream and reduce fatigue, a seat structure makes a slight sitting posture change by adding a minute body motion with no necessity of moving a cushion frame or a seat frame although it realizes a supporting pressure change at a wide area, not locally, in a seat cushion or a seat back. The seat structure includes a cushioning member for a seat cushion stretched across the cushion frame, and a cushioning member for a seat back stretched across the back frame. The seat structure includes: a lower cloth spring of a seat cushion or a cloth spring of a seat back stretched across the cushion frame or the back frame via a torsion bar; and a cloth spring adjusting member to change a supporting pressure by both cushioning members by adjusting tension of the lower cloth spring or the cloth spring.

  • Publication number: 20080289796
    Abstract: A cooling module includes a heat exchanger, a blower, a fan shroud and an air cleaner unit for filtering air to be introduced into an engine of a vehicle. The fan shroud holds the blower on a downstream side of the heat exchanger with respect to a flow of air passing through the heat exchanger and has an air introducing portion defining an air passage from the heat exchanger to the blower. A front end of the air cleaner unit is offset from the heat exchanger with respect to a horizontal direction. A side wall of the air cleaner unit partly forms the air introducing portion. A clearance is provided between the side wall and the heat exchanger such that air upstream of the heat exchanger is conducted toward a position downstream of the heat exchanger through the clearance.

  • Patent number: 7150828
    Abstract: A drain structure for a fluid filter includes a cap internally forming a drain hole. The cap receives a valve member urged by an urging means in a direction, in which the valve member blocks the drain hole. Normally, the drain hole is blocked with a drain member. When fluid is drained from the drain hole, the drain member is removed from the drain hole, and a drain tool is inserted into the drain hole, so that the drain tool displaces the valve member in a direction, in which the drain hole is unblocked. The drain tool has a hooking portion that can hook to a hooked portion provided to the cap by axially rotating the drain tool inserted into the drain hole of the cap. Thus, the drain tool can be connected with the cap while the hooking portion is supported by the hooked portion.
