PURPOSE:To avoid the uneven revolution and oscillation of a motor and a pulley from being delivered to a running body, by making a guide bush made of synthetic resin closely contact with a guide rod and inserting it freely slidably. CONSTITUTION:Two guide rods 10 and 11 are located in parallel with both sides of a holding running body 9 of the 1st mirror 3. A hole 9a is formed at one end of the running body 9, and a guide bush 9b made of a synthetic resin is fixed to the hole 9a with pressing, the guide bush 9b is made closely contact with the guide rod 10 and inserted freely slidably. Guide bushes 13d and 13e of synthetic resin are fixed to a hole 13c of a leg 13b and a hole 13a at one end of the running body 13 of the 2nd mirror 4 with pressing, and guide bushes 13d and 13e are made closely contact with the guide rod 10 and inserted freely slidably. |
