  • Patent number: 10124774
    Abstract: A vehicle pedal device including a transmission member that transmits an operation force applied to a pedal, a reaction force lever that is disposed on the transmission member so that the reaction force lever pivots about a predetermined axis, and that outputs the operation force transmitted to the transmission member to a brake device against a biasing force of a load spring, and a depressing force detector that is fixedly attached to a pedal arm of the pedal or to a sub lever coupled to the pedal arm and that receives a reaction force of the reaction force lever to detect the operation force applied to the pedal, the depressing force detector being configured to have a positioning pin projecting from the depressing force detector, the pedal arm of the pedal or the sub lever coupled to the pedal arm being configured to have a positioning pin insertion hole in which the positioning pin of the depressing force detector is inserted, the depressing force detector being configured to be fixed to the pedal arm or

  • Patent number: 9702479
    Abstract: Valve device is provided with poppet valve for opening and closing flow path. Thread part is formed on shaft of this poppet valve, and driving gear is screwed into this thread part. Driving gear is rotated via pinion by motor, and thereby the poppet valve is moved to advance and retreat so as to control opening and closing of the flow path. Driving gear is provided so as to be able to advance and retreat in the axial direction of the pinion and the axial direction of the poppet valve while remaining engaged with pinion, and is normally held at a predetermined non-operating position by spring (biasing means). With this, even when the poppet valve is seated on the valve seat and has stopped moving, the driving gear moves, when further rotated, against the biasing force of spring from the non-operating position in the axial direction, and absorbs an impact that is applied to the driving means or the like. Damage of the driving means and the like due to the impact load can be prevented.
