摘要： A fluid damper device may include a tube-shaped case including a bottom wall, a tube part extended from the bottom wall, and a partitioning protruded part protruded to an inner side from an inner peripheral face of the tube part, and a turning shaft including a body part facing a first end face of the partitioning protruded part, and a flange part which is enlarged from the body part and faces a second end face of the partitioning protruded part, a valve body supported by the body part, and fluid filled within the case. The first end face of the partitioning protruded part is provided with a first rib protruded toward the body part and extended in the axial line direction and a second rib protruded toward the body part and extended in the axial line direction at a position separated in a circumferential direction from the first rib.

摘要： A rotation transmission mechanism may include a plurality of rotation transmission members having a drive wheel and a driven wheel, and an urging member which urges the driven wheel in a reverse direction to a rotational direction by power of the drive source. The drive wheel and the driven wheel are provided with engagement parts structured to transmit turning of the drive wheel to the driven wheel, the drive wheel is provided with a cam face forming part on which the engagement part of the driven wheel is slid at a rotational position where the engagement parts are not engaged with each other, and a brake member structured to generate a rotation load is disposed in a range on an upstream side of a power transmission path including the drive wheel with respect to the driven wheel in the power transmission path transmitting the power of the drive source.
