PROBLEM TO BE SOLVED: To provide a sucker advantageous in mounting on a sucked face in a stable state with no rattling even when the sucked face is a curved face. SOLUTION: When an accessory mounting portion 16 is pushed against the sucked face 2, a sucking disc 12 sucks the sucked face 2. When a hand is released from the accessory mounting portion 16, a pressing member 18 presses an outer peripheral portion of the sucking disc 12 via elastic portions 40, 42 with the energizing force of first and second coil springs 34, 36, while a central portion of the sucker 12 is forcibly displaced in the direction of leaving the sucked face 2. The pressing member 18 consists of a first member 30 and a second member 32 separately assembled on a center shaft 14 and set apart from each other for abutting on the outer peripheral portion on a back face 24 of the sucker 12 at peripherally different positions. Even when the sucked face 2 is a cylindrical face or the other curved face, the outer peripheral portion of the sucker 12 is pressed following the curved shape of the sucked face 2.
