PROBLEM TO BE SOLVED: To solve the problem in which: in a configuration in which a coupling member has a sphere to be the center of tilt (tilt movement), a torque transmission target member has an opening having a smaller diameter than that of the sphere, and the sphere is brought into contact with an inner edge of the opening to regulate the coupling member from dropping off from the torque transmission target member, the inner edge of the opening may limit the amount at which the coupling member can tilt (make tilt movement).SOLUTION: While a pin 88 that is a shaft part is inserted into a hole 86b that is a through hole provided on a coupling member 86, both edges of the pin 88 are supported with a drive-side flange 87 that is a torque transmission target member. In this way, the coupling member 86, the drive-side flange 87, and the pin 88 are connected with one another, and the pin 88 is brought into contact with the inside of the hole 86b without limiting the amount at which the coupling member 86 can tilt (make tilt movement), and thereby the coupling member 86 can be regulated from dropping off from the drive-side flange 87. |
