A strap holding structure for an electronic device includes a body, a strap holder and a latching element. A power tool has a brushless motor which includes a rotor 133 having a permanent magnet, a cylindrical stator, and three-phase stator windings which are installed on an inner circumferential side of the stator and rotationally drive the rotor. Further, such information is also used to adjust timing andor lift of the valve in the engine cylinder. No manual switching or hot-key sequence by the user is required, and the active data processing system may be automatically switch among any of a number of data processing systems simply by moving the cursor across logical display area boundaries between the data processing systems. Each of the unit cells includes a select element including first and second terminals and a control terminal to which a control signal is input, and a memory element including a third terminal connected to the first terminal and a fourth terminal connected to the second terminal. The distal attachment piece of the connection piece according to the present invention has a locking element which is designed in such a way that a releasable form-fit connection can be made to a connection piece of a probe tube of an enteral feed probe that has a locking element complementing the locking element of the distal attachment piece.
