A door lock apparatus with safety switch capable of locking a door. A coupling member is pivotally moved about a pivotal shaft by a closing operation by a rotary handle, thereby bringing an engaging portion thereof into engagement with a fixing member, so that a protective door is inhibited from moving in two directions of arrows X, Y including a moving direction of the door. Whether the door is of a slide or pivot type, the door is assuredly locked in a closed state because the door is inhibited from moving in the two directions including the moving direction thereof. If an operation mistake is made to open the door, the force for opening the door is not directly applied to the switch body or the actuator. A safety switch may achieve an increase in durability.

Door lock device with safety switch

A safety holder is provided that firmly attaches to a safety switch so that safety of a worker is enhanced. The safety holder includes a base bodythat is inserted into an actuator insertion opening, and limits rotation of a drive camby engaging at a tip end portion (hanging portionC) thereof with a concave portion of the drive camof the safety switch, and a slide body that is movably attached to the base bodyso as to be insertable into an actuator insertion openingwith the base bodyinserted in the actuator insertion opening, and when the slide body is inserted into the actuator insertion opening, that enters and engages with an engagement holeof the base bodywhose tip end portion (insertion arm) is being inserted into the insertion opening
