Patent number: 10626946Abstract: A damper includes a piston and a cylinder housing the piston, and generates a braking force based on a movement or relative movement of the piston. The piston includes a trunk portion and a seal ring surrounding the trunk portion. A first seal portion against an inner wall of the cylinder is formed on an outer peripheral portion in the seal ring, and a second seal portion against a circumference wall portion projecting from the trunk portion is formed in a front end portion positioned on a pressure chamber side. Also, a support rib portion is provided outside the trunk portion, which allows the seal ring to move within a predetermined range along a moving direction of the piston in a state wherein a movement gap for a fluid is formed between the trunk portion and an inner peripheral portion of the seal ring.Type: GrantFiled: September 16, 2016Date of Patent: April 21, 2020Assignee: NIFCO INC.Inventor: Kei Shimozaki

Patent number: 9103390Abstract: A rotary damper device with a one-way clutch includes a rotary damper having a damper housing having a viscous fluid sealed inside, and a rotor having a rotor blade received rotatably inside the damper housing and a rotor shaft; and the one-way clutch including an inner member having a recessed portion on an outer perimeter portion and coaxially joined to the rotor shaft, an outer member having an inner gear, and a gear housed in the recessed portion to engage with the inner gear. When the outer member rotates in a positive direction, the outer member rotates independently from the inner member. When the outer member rotates in a negative direction, the gear couples and the outer member and the inner member rotate together. The inner member has a portion larger than the rotor shaft. The outer member has a locking portion to be locked on the inner member.Type: GrantFiled: May 15, 2012Date of Patent: August 11, 2015Assignee: NIFCO INC.Inventor: Kei Shimozaki

Patent number: 8857881Abstract: To easily handle a drawer device for a combined use as a container box and a cup holder to selectively use as the container box or the cup holder without requiring a troublesome operation. A connecting mechanism (80) is provided, which connects both a cup holder plate (50) and a tray (20) in a case wherein both are housed inside a housing (12) from a state wherein both are drawn to the maximum drawn position, and separates a connection between the cup holder plate (50) and the tray (20) in a case wherein the tray (20) is housed inside the housing (12) from a state wherein only the tray (20) is drawn to the maximum drawn position.Type: GrantFiled: March 23, 2010Date of Patent: October 14, 2014Assignee: NIFCO Inc.Inventor: Kei Shimozaki

Publication number: 20140001007Abstract: A rotary damper device includes a damper housing enclosing a viscous fluid; a rotor having a rotor vane rotatably received inside the damper housing, and a rotor axis protruding to an outside of the damper housing; and a rotary member combined with a protruding end of the rotor axis. The rotary member includes an insertion hole through which the protruding end of the rotor axis passes, and a pair of control walls at a hole edge with the insertion hole interposed therebetween. A protruding end of the rotor axis protrudes in a radial direction of the rotor axis along a gap between the pair of control walls so as to be engaged with the hole edge of the insertion hole by being heated and deformed in a state wherein the protruding end of the rotor axis has passed through the insertion hole.Type: ApplicationFiled: January 10, 2012Publication date: January 2, 2014Applicant: NIFCO INC.Inventor: Kei Shimozaki

Publication number: 20120055748Abstract: A damper device includes a cylinder body, and a piston body. At least one end of either the cylinder body or the piston body is linked to an object to be braked to brake a relative movement or a movement of the object to be braked. The cylinder body includes a blocking member made of a synthetic resin at a deep inner section opposing to the piston body. The blocking member is formed separately from the cylinder body, and installed in one end of a tubular-shaped body forming the cylinder body. The blocking member has a fluid passage section and a braking force variable member moved therein. The braking force variable member holds passage of a fluid passing through the fluid passage section at a time of a movement of the piston body in a direction leaving from the deep inner section.Type: ApplicationFiled: August 29, 2011Publication date: March 8, 2012Applicant: NIFCO INC.Inventors: Yusuke Imai, Kei Shimozaki, Yoshitsugu Homma

Publication number: 20080099647Abstract: A glass holder, used when a window glass is attached to a connection portion, includes a first supporting plate portion; a second supporting plate portion; and a hinge portion disposed between the first and second supporting plate portions so that the first and second supporting plate portions face each other. Through-bores are disposed at the first and second supporting plate portions. A temporary locking device projects from one of the two supporting plate portions to be able to lock with the window glass by being inserted into the mounting bore in a non-clamped condition where the supporting plate portions open through the hinge portion.Type: ApplicationFiled: October 18, 2007Publication date: May 1, 2008Applicant: NIFCO INC.Inventor: Kei SHIMOZAKI
