PURPOSE: To easily change the layout relationship between a contact for detection and a contact for guide according to the change in measurement conditions, etc., and to measure load other than tension by supporting the contact for guide by an accessory body separate from the case and making the accessory body freely detachable from the case. CONSTITUTION: A rectangular accessory body 21 which is nearly of the same shape as a case 1 is mounted to the reverse side of the head part of a case 1 with a screw 22 through a vertically long mounting hole 25, and each contact 8 for guide of a roller shape is projected through a support body 5 at both sides of the top part of the accessory 21 so that a contact 4 for detection on the case 1 may be held between them. The accessory body 21 can be adjusted vertically, and the layout relationship between the contact 4 on the case 1 and the contact 8 of the accessory body 21 can be adjusted by adjusting the mounting position. Therefore, in measuring a tension, a bend angleθof a section L can be set to a specific angle in advance by adjusting the layout relationship between both contacts 4 and 8. The layout relationship can be adjusted by exchanging the accessory body 21 itself or adopting the displacement mechanism of the contact 8 on the accessory body 21.
