PROBLEM TO BE SOLVED: To provide a coupling structure and a connection part which sufficiently absorb a rotational force in a horizontal plane that is applied to a connected handrail and also enable the interval of connection parts relative to a flange to be specified. SOLUTION: The connection part 3 comprises parallel connection parts 31,32 and a continuous part 33 interposed therebetween. The connection parts are vertically arranged relative to a peripheral flange 2 mounted on a pipe support 1 and are engaged with a wedge 5. The continuous part 33 is attached with the handrail 4. Respective end edges 31a of the connection parts are provided with arcuate abut parts for abutting on the support. Both side edges of one connection part are provided with protruding parts 34a, 34b to protrude uniformly in the opposing direction of protrusions of the other connection part. At least one of the protruding parts has stoppers 36a, 36b at positions with a specified distance apart from the abut part for abutting the support. COPYRIGHT: (C)2004,JPO
