Document Type and Number:
Japanese Patent JP7442622
Kind Code:
B2
Abstract:
A rotary operating device includes a case, a rotating shaft member, an operation member, and a sensor. The case has a cavity having an annular shape with an opening at a top. The rotating shaft member is rotatable with respect to the case. The operation member rotates together with the rotating shaft member. The sensor is disposed within the cavity to detect rotation of the rotating shaft member. The case has an inner peripheral wall. The operation member has an inner cylindrical portion. The rotating shaft member has a peripheral wall that extends downward and along an outer peripheral surface of the inner peripheral wall. A first gap between the inner peripheral wall of the case and the peripheral wall of the rotating shaft member is smaller than a second gap between an inner peripheral surface of the rotating shaft member and the inner cylindrical portion of the operation member.
