Abstract: An engagement section of a pole and a protruding section of an upper arm restrict movement of the pole outward in the radial direction and disable meshing of outer teeth and inner teeth, when the relative rotation angle of a lower arm and the upper arm is within a prescribed range. Outer teeth and the inner teeth of poles cannot engage as a result of the restriction on movement of the pole outward in the radial direction. The amount of movement by the poles separating from the inner teeth along the radial direction is set so as to be greater than the amount of movement by the pole separating from the inner teeth along the radial direction, when the pole reaches a position corresponding to where the outer teeth and the inner teeth cannot mesh as a result of the protruding section, etc., during the unlock operation.

Abstract: A seat reclining device includes a pawl having external teeth, a first arm, a second arm, a cam assembly, and a pressing member. The first arm has a pair of guide walls that guide the pawl in the radial direction. The second arm is rotationally supported by the first arm and has internal teeth. When the cam assembly rotates in a forward direction, the cam assembly presses and moves the pawl radially outward to mesh the external teeth with the internal teeth, and presses the pressing member radially outward. When pressed radially outward, the pressing member presses the pawl in the radial direction and a direction from the guide wall towards the pawl. When the cam assembly rotates in a reverse direction, the cam assembly releases the pressing member and moves the pawl radially inward to separate the external teeth from the internal teeth.

Abstract: A charge and discharge control unit (41) sets an upper-limit charge and discharge electric power as an upper limit of electric power during charging and discharging of a electric storage device (11) based on temperature of the electric storage device (11) measured by a temperature measuring unit (21) and a state of charge of the electric storage device (11) specified by a charge state specifying unit (23). In the case where the operation state determined by an operation state determining unit (35) is a low-limit operation state, the charge and discharge control unit (41) sets the upper-limit charge and discharge electric power to be larger than that in the case where the operation state determined by the operation state determining unit (35) is a high-limit operation state.
