摘要： PROBLEM TO BE SOLVED: To prevent slipping off from a case without using any locking piece for preventing a connecting plate from slipping off, by providing a pusher capable of being freely slid in relation to a case, to be engaged with the connecting plate, for regulating slipping off, and for releasing the engagement of an electric wire and the tip of a contact locking plate by pressing. SOLUTION: When electric wires 7, 8 are inserted into electric wire inserting holes 9, 10, they are brought in contact wit the tip and the intermediate part of a contact locking plate of a terminal body 11, and the electric wires 7, 8 and the terminal body 11 are electrically and physically connected to one another. When the wires 7, 8 are to be drawn from the terminal structure, the tip of the contact locking plate bites core parts 7', 8' of the electric wires, and the electric wires can not be drawn. Since the tip of a pressing and locking projecting piece presses down the tip of the contact locking plate when the pusher 23 is pressed, the engagement of the tip and the core parts 7', 8' of the electric wires is released, nothing latches the electric wires 7, 8. Accordingly, the electric wires 7, 8 can be easily drawn out.

摘要： PROBLEM TO BE SOLVED: To provide a power tool motor controlling device of a very simple structure and whose oscillation circuit which drives a switching element is also constituted of a very simple circuit. SOLUTION: This motor control device comprises a drive power supply 1, a motor 3 connected in series to this power supply 1, a switching element 4, an oscillation circuit 6, which makes variable the on-off duty cycle of square waves to be outputted and drives the switching element 4 on outputted signals, and a power-supplying means 5, which applies to the oscillation circuit 6 the drive power supply voltage applied to the motor 3 and switching element 4, without providing a switching means in between.
