ABSTRACT:
A rotation deceleration device used for a sanitary cleaning device which includes a toilet seat and a toilet cover and is attached to a toilet bowl, thereby injecting warm water in the toilet bowl. The rotation deceleration device includes a cylinder having a hydraulic chamber filled with a control oil; a rotation shaft inserted through the cylinder; a control wall radially projected from the rotation shaft to divide the hydraulic chamber into at least two sub chambers; a control valve provided between the control wall and an inner surface of the cylinder. The control valve has a closing wall opposed to a side surface of the control wall so as to be attachable thereto and also has an engaging member opposed to the other side of the control wall so as to be engageable therewith in accordance with the rotation of the rotation shaft. The control valve is formed of a material which has a higher coefficient of thermal expansion than that of a material forming the control wall and the cylinder.
