To provide a hiding hinge having an automatic closing function.

This hiding hinge has an automatic closing device 12, a pair of first links 18 and 20 mutually extending in plane symmetry from first and second cylindrical members around a virtual plane including the axis of the first and second cylindrical members 14 and 16 of the automatic closing device, a pair of slides 26 and 28 rotatably and continuously connected to the first links, a pair of supports 30 and 32 slidably engaged with the slides, second links 22 and 24 set on the opposite side of the virtual plane to its first links in the first and second cylindrical members, a pair of third links 38 and 40 having the first end rotatably connected to the second links and the second end rotatably and continuously connected to a support member, and a displacement mechanism for displacing the supports slidably engaged with the slides rotatably and continuously connected to the respective first links in the direction for relatively separating from the first links by moving the first links in the mutually separating direction by continuously connecting the third links and the slides.
