<P>PROBLEM TO BE SOLVED: To provide an armrest structure of a portable toilet, allowing a user to easily release turn restriction of an armrest with a simple structure. <P>SOLUTION: A lever 11 of the armrest 10 of the portable toilet has an operation part 111 and an action part 112. A wire 12 is connected to the action part 112, and a lock pin 13 is connected to the wire 12 in the rear part of the armrest 10. A frame side attachment restricts the turn of the lock pin 13. A torsion spring 15 energizes the lock pin 13 toward the frame side attachment. A lever stopper 16 restricts the turn range of the lever 11. A fixed part 182 abuts on a fixing base 17 when the armrest 10 horizontally extends. The lever 11 changes over the direction of force applied to the action part 112 to a direction along the back-and-forth direction of a frame 7, pulls the wire 12, and releases the turn restriction of the lock pin 13 by the frame side attachment. The fixing base 17 is disposed below the armrest 10 in front of a turn shaft 181 of the armrest 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
