  • Publication number: 20240060550
    Abstract: A toothed cable includes a cable body, and a cap provided at a tip of the cable body. The cap includes a conical tip portion, and a cylindrical body portion provided on a side of a base end of the tip portion, when the toothed cable moves in a direction from a side of the cap toward a side of the cable body in a curved guiding path of a guide member, the cap moves so as to be in sliding contact with an outer wall portion, and the toothed cable is configured such that an end region of the cable body, which end region is on the side of the cap, contacts an inner wall portion of the guide member when the cap comes into sliding contact with an edge of a concave portion of the guide member to limit an angle ? at which the cap swings.

  • Patent number: 11892021
    Abstract: A connection structure is provided, wherein relative movement between outer and inner members is restrained by an engaging member. The engaging member includes first and second bolding elements. A connection part connected to another-side end part of the second holding element is provided in one-side end part of the first holding element. A first extension part is provided in another-side end part of the first holding element The connection part includes second and third extension parts, and a connection element extending substantially parallel to the second holding element. The first holding element and the first and second extension parts are provided such that an angle formed by the first holding element and the second extension part, and an angle formed by the first holding element and the first extension part are smaller than 90°. Use of the connection structure, which is easily formable, restrains the engaging member from being detached.

  • Patent number: 10995790
    Abstract: An elongate member assembly having an elongate member, a connecting member provided between one end and another end of the elongate member, and a swaging member that swages and fixes the connecting member to the elongate member, and fixing member connected to the connecting member. The connecting member includes a swaging portion pressed by the swaging member on the elongate member, and a connecting portion connected to the fixing member. The fixing member includes an anchor portion mounted to a mounting object member, and a ring-shaped portion connected to the connecting portion. The connecting portion includes, a rotation permitting portion that permits the ring-shaped portion to move, and a movement limiting portion that limits movement of the ring-shaped portion. The elongate member assembly facilitates the fixing thereof onto the mounting object member.

  • Patent number: 10359070
    Abstract: A seal structure includes an insertion path which connects between a first opening and a second opening and through which a longitudinal member is inserted; and a seal part, formed at the intermediate section of the insertion path, which contacts with the outer circumference of the inserted longitudinal member. A discharge path is provided on a side wall section of the insertion path, and connects from the side surface of the side wall section to a section, of the insertion path, which is closer to an inflow opening through which flowing water is likely to flow than the seal part is to the inflow opening.
