PURPOSE: To provide a table provided with a lock device for restricting a top plate supported so as to be freely rotatable in horizontal and erect attitude.
CONSTITUTION: In the upper end of a support 1, a top plate 2 is supported so as to be freely rotatable through a first supporting shaft, and also, an operating lever 10 is supported so as to be freely turnable by a second supporting shaft 11 provided at a necessary interval in the vicinity of a first supporting shaft. On the other hand, this table is constituted so that a lock pin 12 provided in the top plate 2 is slidably fitted in a guide groove 13 provided on the way of length of the operating lever 10 so that the lock pin 12 moves freely along the guide groove 13 at the time when the top plate 2 rotates, and when the top plate takes a horizontal attitude, the attitude is restricted by detaining the lock pin 12 into a first detaining part 14 of one end part of the guide groove 13, and when the top plate takes as erect attitude, it can be restricted to the erect attitude by detaining the pin into a second detaining part 15 of the other end.
