  • Patent number: 10625633
    Abstract: A lifter includes a pinion gear meshed with an input gear of a link mechanism that lifts and lowers a seat. A rotation control device that controls rotation of the pinion gear includes a rotation restriction mechanism. The rotation restriction mechanism includes a sub-meshing member which meshes with a meshed member together with a main meshing member. The sub-meshing member is displaceable to gradually release the meshing of the sub-meshing member with the meshed member when the meshing between the meshed member and the main meshing member is released.

  • Patent number: 9778140
    Abstract: An engine testing apparatus is provided with a memory portion for storing a control command value obtained when the rotation speed of a dynamometer is changed by the control command value in accordance with the change of the engine rotation speed in a real vehicle in a period in which the engine behavior in a real vehicle is reproduced without connecting the dynamometer to an engine under test. The engine testing apparatus is provided with an output portion that supplies the control command value stored in the memory portion to the dynamometer with reference to an engine output signal showing the start of the reproducing period.

  • Publication number: 20130330146
    Abstract: In a screw installation structure in which a first member, made of an iron-based material and having a male screw-threaded portion, is fixed to a second member, made of an aluminum-based material and having a screw hole, by screw-threaded connection between the male screw-threaded portion and the screw hole, a non-circular deformed portion is partly formed on an outer periphery of a portion of the first member, exposed from the screw hole of the second member. Also provided is an anti-rotation and anti-loosening member configured to be brought into fitted-engagement with the non-circular deformed portion. The anti-rotation and anti-loosening member, in fitted-engagement with the non-circular deformed portion, is brazed onto a surface of the second member in wall contact with a contact surface of the anti-rotation and anti-loosening member, so as to prevent loosening of the first member relative to the second member.
