A tensile strength tester feasible of the present invention is feasible for automation and includes a rotating member and a pulling member connected to each other. A torque is transferred from the rotating member to the pulling member with a counterforce being absorbed at the position where the two members are connected. Such a connecting portion is prevented from becoming loose. The tester is capable of measuring a tensile strength when a screw member fitted in a base material is pulled out of the base material.

A rotary power tool having a device for detecting the torque of a rotatable shaft. The tool resets a peak torque of the shaft held therein in associated with fastening work. Hence, screws, for example, can be continuously driven without resorting to a switch or similar extra resetting means.

In a copier, a document pressing device has a holder member pivotally engaged with a base member at its base end. A bracket is pivotally connected to the other end of the holder member by a shaft. An inner sleeve has its bottom pivotally engaged with a lug formed on the base member and positioned closer to a glass platen than the base end of the holder member. An outer sleeve has its bottom pivotally connected to the free end of the bracket and positioned closer to the glass platen than the point about which the bracket is pivotable. When a relatively thick document is laid on the glass platen, the device allows a cover for pressing the document to be smoothly lifted up or returned to its original position. The device, therefore, enhances the manipulability of the cover plate.
