Dogs (switch operation members) 2a and 2b are engaged with a supporting shaft 15 bridged between a pair of fixed members 12a and 12b on the base plat 10 to operate a limit switch 18. Due to springs 3a and 3b, deviation between a limit positions of the dogs 2a and 2b and a limit position of the lifting part 30 can be absorbed.
