To provide a protrusive fixture for attachment to a wall capable of simply solving the ricketiness of an attachment state to the wall without removing a cap after construction and also capable of simply performing separation.
A protrusive fixture for attachment to a wall W includes a body 1 of a hollow structure and a cap 2 fitted to an opening of the tip side, and is fixed to the wall W by inserting a shaft 11a of an attaching screw 11 to a through-hole 3 formed on the base edge side of a body 1 and screwing the attaching screw 11 into the wall W in which an angular engagement hollow spot 4 which communicates with the through-hole 3 and causes a head 11b of the attaching screw 11 to be engaged therewith in accordance with rotation is formed on the base edge side of a hollow part of the body 1. The attaching screw 11 is screwed into the wall W and the body 1 is closely joined to the wall W side only by rotating the outer circumference of the body 1 while holding the outer circumference of the body 1 by hand. Therefore, ricketiness can be solved without separating the cap 2 by a simple operation. Furthermore, only by rotating the outer circumference of the body 1 in a direction reverse to a direction upon attachment while holding the outer circumference of the body 1 by hand, separation from the wall W can be performed.
