A pair of latch membersR,L in a caseC protrudes from an outer face of the caseC by a springand when the caseC is passed through a wall holeH, the latch membersR,L are narrowed by an engagement between outer edge (guiding) slant faceROI,LOI and a wall holeH and after the caseC has passed through the wall holeH, the latch membersR,L are spread by a springso as to engage the engagement slant facesRLI,LLI with the wall holeH and also while fixing temporarily the caseC to the walltogether with a flangeFL of the caseC. After that, a screwis screwed to draw the nuttoward the flangeFL and to engage securely the latch membersR,L held to the nutwith the wall holeH to complete secure fixing of the caseC.

Wall through fixture device

Provided is a hook which is capable of holding multiple objects or an object having a large size of width by efficiently using a space inside the hook, reliably preventing the hanged object from dropping, and allowing the hanged object to be taken out easily. A hook body has a latch that locks an arm biased toward an outside of the hook body by an arm biasing mechanism, and regulates a displacement of the arm, thereby closing an opening portion. While the latch is biased by a latch biasing mechanism so as to face the opening portion and be present at an arm regulating position for locking the arm, the latch is displaced from the arm regulating position against a biasing force of the latch biasing mechanism so as to unlock the arm.

Hook

One end portion and the other end portion of the first linkare respectively rotatably connected to a first housing side attachment memberand a second housing side attachment member. Upper and lower side portions of one end portion of the second linkare respectively rotatably connected to the first and second housing side attachment members. Upper and under side portions of the other end portion of the second linkare respectively rotatably connected to the first and second door side attachment members. One end portion and the other end portion of the third linkare respectively rotatably connected to the second housing side attachment memberand the second door side attachment member. The first, second and third linksare arranged to be spaced from one another in the direction of rotation axes thereof.
