  • Patent number: 11708710
    Abstract: A glove compartment lock device includes: a base member attached to a glove compartment; a knob member supported by the base member so as to be rotatable around a shaft portion between a closed position and an opened position; an arm member supported at a center portion in a longitudinal direction thereof by the base member so as to be swingable between a locked position and an unlocked position of the glove compartment and configured to come into contact with the knob member at one end portion thereof; and a spring member locked at one end portion thereof to the knob member, locked at another end portion thereof to another end portion of the arm member, and configured to generate a biasing force that rotates the knob member to the closed position and swings the arm member to the locked position.

  • Patent number: 11634099
    Abstract: A breakable portion breaks, as a break start point portion, a portion in a vicinity of a center of a tip end side of a door portion away from a hinge portion on a rotation center side of the door portion when the door portion is opened. A breakable coupling portion in an area of the start point portion is disposed such that a width dimension between the breakable openings which are adjacent to each other in a plan view on a tip end portion away from the hinge portion is smaller than a width dimension on a base portion close to the hinge portion of the door portion.

  • Publication number: 20200408010
    Abstract: A lock mechanism, includes: a rotor including a rotor rotation axis, a pair of rod connecting portions, and a pressure receiving surface; a knob including a knob rotation axis and a pressing portion; a locking portion including a pair of rods; a rotor urging member; and a knob urging member. During an opening operation in which the knob rotates from a normal position to a release operation position, the pressing portion pushes the pressure receiving surface while sliding on the pressure receiving surface to rotate the rotor from a lock input position to a release input position, and a length, obtained by projecting a sliding locus of the pressing portion on the pressure receiving surface on a cross-section in an axial perpendicular direction of the rotor, is not less than 0.8 times a length, by which the position of the pressing portion has been actually changed.
