PROTECTOR

A protector (1) includes: a protector main body (10) that houses a protection target part (We1); and a protrusion housing body (20) that is connected to the protector main body (10) and houses a protrusion (Pr) from a wall face (Bd1). The protrusion housing body (20) includes: a first wall body (21) that surrounds the protrusion (Pr) inserted from a first opening (21a); and a second wall body (22) that closes a second opening at another end of the first wall body (21). In order to prevent the protrusion (Pr) from contacting the second wall body (22), the first wall body (21) is formed in a cylindrical body that is longer in a cylinder axis direction than a maximum protrusion amount of the protrusion (Pr) from the wall face (Bd1), and the second wall body (22) is interposed between an external wire (Weh) and a tip of the protrusion (Pr).
