A harness protector for accommodating a wire harness in a protector main body in a curved shape includes a friction member for holding the wire harness in the accommodating state temporarily. The friction member abuts resiliently on the wire harness. The harness protector is provided on a sliding member or a fixed member. The wire harness is wired from the harness protector to the sliding member and the fixed member. The friction member temporarily prevents the wire harness from being removed while the sliding member moves. A spring member for biasing the wire harness in a direction where the wire harness is accommodated is provided in the harness protector. The wire harness compresses the spring member to the maximum at a first moving end of the sliding member. The friction member is disposed at a position so as not to interfere with a restoring of the spring member during moving the sliding member from the first moving end to a second moving end.
