  • Patent number: 11773631
    Abstract: A cover opening-closing device comprises a rod, a casing in which at least a portion of the rod is stored, a lock unit, an interlock mechanism, and a connection unit. The lock unit can rotate about a central axis line between a lock position, in which locking with the cover is possible, and a release position, in which locking is not possible. The interlock mechanism is configured so that the rotation of the lock unit and the displacement of the rod are interlocked. The connection unit is configured so as to connect the lock unit to the casing and to restrict displacement of the lock unit in the direction of the central axis line.

  • Patent number: 11505028
    Abstract: Provided is a vehicular holding device that, in an ON state, holds a vehicle component in a state where displacement of the vehicle component in an axial direction is restrained, and that, in an OFF state, holds the vehicle component in a state where displacement of the vehicle component in the axial direction is possible. The vehicular holding device includes at least one engagement part, a cam mechanism, and an axial direction restraining part. The at least one engagement part is at a position where the engagement part engages with an engaged part in the ON state, and is at a position where the engagement part is separated from the engaged part in the OFF state. The cam mechanism displaces the at least one engagement part from the OFF-state position to the ON-state position. The axial direction restraining part receives axial-direction force acting on the at least one engagement part.

  • Patent number: 10920821
    Abstract: [Problem] To provide a terminal securing device the size of which can be reduced. [Solution] When a key lock 7 is positioned in a second position a key 6 and the key lock 7 are arranged at overlapping positions in the lengthwise direction of a rod 3, so a portion of a space for displacing the key lock 7 from the second position to a first position can be provided at a position overlapping the key 6 in the lengthwise direction of the rod 3. Thus, an increase in the size of a holder 4 in the lengthwise direction of the rod 3 can be avoided, so the size of the terminal securing device 1 can be reduced.

  • Patent number: 10809054
    Abstract: Provided is a shape measurement device that measures a shape of a spiral spring formed in a spiral shape. The shape measurement device is provided with an input means and a function calculation means. The input means inputs a captured photographic image depicting the spiral spring or measurement data produced by measuring the shape of the spiral spring. The function calculation means uses the input photographic image or measurement data to calculate at least an inter-coil space function representing the space between neighboring coils of the spiral spring, a pitch function representing the distance between coil cores of neighboring coils of the spiral spring, or a coil thickness function representing the thickness of coils of the spiral spring.
