PROBLEM TO BE SOLVED: To easily and efficiently attach spacers without taking an unnatural posture. SOLUTION: This spacer 1 comprises a trapezoidal supporting bed 2 curved in a lower part of rearward thereof, an engaging part 5 for engaging with a welded wire mesh W which is concrete reinforcing metal wire, and an operating part 4 for rotating the bed 2. When the spacer is attached, a hooking part 6 of the engaging part is hooked on a reinforcing bar V of the welded mesh W to pull down forward the operating part 4. The bed 2 is then rotated around the reinforcing bar V engaged with the hooking part 6, and the rearwardly lower part of the bed 2 is moved backward on foundation X. The bed 2 enters a lower part of the reinforcing bar V to become a state of sitting straight, and the reinforcing bar V is supported on an upper part of the bed 2 in a state sandwiched between the hooking part 6 and a fixing part 7 of the engaging part. That is, leverage using the rearward lower part of the bed 2 as a movable fulcrum, the operating part 4 as a power point, and the engaging part as a point of action is caused, so that the reinforcing bar V of an attaching place is lifted to get into a lower part by the leverage. Thereby, a worker can work in a state of being on the welded wire mesh W, and can attach it easily by an easy posture.
