Abstract
A joint mechanism includes: a first member; a second member that includes a first portion and second portion; a gear device including a crank shaft on which a first eccentric portion is formed, a first oscillating gear that has first external teeth and a first insertion hole, a carrier that retains the crank shaft, and an external cylinder that has internal-tooth pins. The carrier and the external cylinder are configured to be displaced coaxially due to oscillation of the first oscillating gear. The joint mechanism further includes a first fixing member that fixes the external cylinder to the first member, and a second fixing member that fixes the carrier to the second member. The second fixing member includes a one-side fixing member that fixes the carrier to the first portion and an other-side fixing member that fixes the carrier to the second portion.
