  • Patent number: 10138583
    Abstract: A cloth clamping device includes a clamping mechanism that comes into contact with a cloth and an up-and-down movement mechanism that moves the clamping mechanism up and down. The clamping mechanism includes a support portion, a leg portion, a foot portion, and a clamping portion. The clamping portion has a leading end portion facing the foot portion in a sideway direction and a base end portion being pivotally supported by the support portion. When the leg portion is lowered with respect to the support portion, the leading end portion pivots downward and is positioned in a sideway direction with respect to the foot portion, and when the leg portion is raised with respect to the support portion, the clamping portion comes into contact with the upper surface of the cloth and the leading end portion is positioned above the foot portion, and the clamping mechanism draw up the cloth.

  • Patent number: 7762154
    Abstract: A synchromesh automatic transmission includes a lug lock portion which is engaged with a shift lug separately from a shift finger and enables a shift fork to be controlled so as to be located at a neutral position, a shift selector mechanism which achieves a target shift stage by engaging the shift finger with the shift lug of the shift fork corresponding to the target shift stage and displacing this shift fork in a shift direction, and an interlock mechanism which controls a shift fork that is different from the target shift stage so as to be located at a neutral position by displacing the lug lock portion following movement of the shift finger in a selection direction and engaging this lug lock portion with the shift lug of the shift fork that is different from the target shift stage.
