The screw element33is screwed into a threaded hole32formed in an end plate29of the operation pattern selecting valve16to secure the first bracket34to the end plate29. The fitting portion35aof the second bracket35is fitted to the turn-type control lever30to connect the second bracket35to the turn-type control lever30. The lock36is insertably attached to the respective lock holes34band35fof the first bracket34and second bracket35for locking the turn-type control lever30. With such a structure, the lock device can be manufactured relatively easily without the necessity of processing the operation pattern selecting valve.
