  • Patent number: 10233994
    Abstract: A damper device includes a cylinder, a piston, a seal ring member, and a transmitting portion. The piston includes an annular outer circumferential portion, a first stopper portion, a second stopper portion, and a projecting portion. The projecting portion has an inclined surface which is inclined radially outwards form a side of the second stopper portion towards a side of the first stopper portion. The seal ring member is configured to allow a first chamber to communicate with a second chamber when a portion of the seal ring member which is not restricted by the first stopper portion is deformed in a direction away from the second stopper portion due to friction caused between the seal ring member and the cylinder or a fluid pressure from the second chamber to ride on the inclined surface.

  • Patent number: 10221909
    Abstract: A damper device is configured so that a piston moves in a cylinder. A seal ring member is provided to the outer periphery of the piston to device the inside of the cylinder into a first chamber and a second chamber. A transmission member is connected to the piston and can transmit external force to the piston. A cutout section is formed with a predetermined circumferential width in a first stopper surface. A communication section has an opening in an annular outer peripheral section located closer to the second chamber than the cutout section. When the seal ring member is pressed toward the first stopper surface, the seal ring member is deformed so as to partially enter the cutout section.

  • Patent number: 10220791
    Abstract: One embodiment provides a mounting structure including a hook member to be mounted on a mount member, and a mounting member. A base part of the hook member protrudes from the front side of the mount member. In the mounted state, a locking part of the hook member locks with a back rim of a mounting hole. An operation part of the mounting member is operated during the mounting on the mount member. An engaging part of the mounting member can engage with the locking part at the back side of the mount member. The mounted state is achieved by sliding, via an operation applied to the operation part, the mounting member substantially parallel to a front surface or a back surface of the mounting hole, such that the engaging part engages with the locking part.

  • Patent number: 10071618
    Abstract: The embodiment provides a tonneau cover device. The tonneau cover device includes a tonneau cover and a fixing device to engage with a lock portion to thereby hold the tonneau cover in a pulled-out-and-held state. The fixing device includes: a slider provided in a slidable manner and a hook provided in a swingable manner. When a force is exerted on an engagement protruding portion of the hook as a result of pushing in the tonneau cover toward the winding direction from the pulled-out-and-held state, and the exerted force acting on the engagement protruding portion is larger than the normally-given urging force acting on the engagement protruding portion, the hook swings such that the engagement protruding portion retracts into the case while causing the slider to be pushed in away from the sidewall, thereby being disengaged from the locking portion.

  • Patent number: 10047818
    Abstract: A damping device has a pin member inserted slidably in a cylindrical case member. The bottom of the case member has: a hole forming section in which an insertion hole is formed; and a slit for allowing the hole forming section to be expanded and deformed. The outer peripheral surface of the pin member and/or the inner peripheral surface of the hole forming section has a tapered section tilted relative to the axial direction. The movement of the pin member of being pressed into the insertion hole from the inside causes the outer peripheral surface of the pin member and the inner peripheral surface of the hole forming section to slide on each other along the tapered section, and as a result, the insertion hole is expanded.
