PROBLEM TO BE SOLVED: To provide a remote control for a toilet, and toilet equipment equalizing radio wave receiving sensitivity from the remote control even if a radio obstacle such as the human body exists between the remote control and a receiving antenna of the toilet equipment when installing the remote control on either right or left wall in a toilet room. SOLUTION: An antenna part 7a for the left transmits radio wave mainly to the left, and an antenna part 7b for the right transmits radio wave mainly to the right. Consequently, even if the obstacle such as the human body exists between the remote control 1 and the receiving antenna, radio wave receiving sensitivity from the remote control is the same. The phase of transmit radio wave is made different between the left and right antenna parts 7a, 7b by a phase circuit 12. COPYRIGHT: (C)2007,JPO&INPIT
