PROBLEM TO BE SOLVED: To facilitate wiring connection work and to easily confirm an engagement state of a terminal that is provided in a wiring end portion to a terminal screw.SOLUTION: A screw-up type terminal block device comprises: a terminal fitting 2 in which a screw hole 2a is provided and which is held while being insulated from a substrate; a terminal screw hold member 5 including a parallel moving part 5a which is engaged to the substrate in a freely movable manner within a predetermined range in parallel with an axial direction of the screw hole, and a terminal screw locking part 5b which is provided protrusively in counter to the terminal fitting and locks a terminal screw 3 that is threaded into the screw hole, in a freely rotatable manner relatively to the parallel moving part; and an elastic member 4 which is mounted between the substrate and the terminal screw hold member and moves the terminal screw hold member up from the terminal fitting in such a manner that the terminal screw is separated from the screw hole when the terminal screw is loosened from the screw hole. The terminal screw locking part is coupled to the parallel moving part via a rotatable member 7A in such a manner that an interval with the opposite terminal fitting can be widened at an insertion side of wiring 8 to be connected.SELECTED DRAWING: Figure 2 |
