A rotary connector device includes a fixed body, a rotation body, a connector, and an electrode. The connector is coupled to the fixed body and includes a second space and a cable cutting member in the second space which is in communication with the first space. The electrode is provided in the second space of the connector. An exposed conductor portion provided at one end of a cable is connected to the electrode. The cable extends from the second space to the first space. The other end of the cable is connected to the rotation body. The cable cutting member is configured to cut the cable before the exposed conductor portion connected to the electrode of the connector is disconnected when the cable is pulled due to rotation of the rotation body.

Rotary connector device

A rotary connector device includes a fixed body, a rotation body, and a connector. The rotation body is rotatable about a rotation axis with respect to the fixed body. The rotation body is assembled to the fixed body in a manner to form a first space between the rotation body and the fixed body. The connector includes a second space. The connector includes a first opening and a second opening. One end of a first cable is connected to a first electrode provided in the second space. One end of a second cable is connected to a second electrode provided in the second space. The first cable passes through the first opening. The other end of the first cable is connected to the rotation body. The second cable passes through the second opening. The other end of the second cable is connected to the rotation body.

The object is to allow rotatable rollers to rotate smoothly. Rotatable rollers axially supported by bearings provided in a retainer so as to be rotatable include legs, each of which has an engaging part engageable with the corresponding bearing. A sliding part of the leg which is slidable against an inner circumferential surface of the bearing has a cross-sectional shape which is contactable with the inner circumferential surface over a width smaller than a width of the leg.

Rotatable connector device

A stator and a rotator, which relatively rotate concentrically with a steering, are formed. A torque transmitting portion, which transmits a rotation torque of the steering to an angle detection rotating body provided in an angle detection sensor for detecting a rotation angle of the steering, is formed concentrically with the angle detection rotating body. Fitting portions for fitting to fitting allowance portions, which are formed on at least a part of a circumferential direction of the angle detection rotating body, are formed on the torque transmitting portion. Fitting abutting portions of the fitting portions, which fit and abut against the fitting allowance portions, are formed in shapes tapered toward the fitting allowance portions.
