However, the first magnet 151 may be disposed such that the N pole faces the second slide member 142 and the S pole faces the first body 110.

In addition, the first magnet part 151 may be located between the first body 110 and the first slide member 141, that is, in front of the first slide member 141 so as not to be exposed to the outside from the first position. Preferably, it may be disposed on the rear surface of the first slide member 141.

In order to implement the deceleration part, the first slide member 141 may be formed of a conductive material having a conductivity of 10 ⁷ (mhos / m) or more, and copper or aluminum may be used as examples. .

As the first slide member 141 passes through a magnetic field formed between the first and second magnets 151 and 152, a change occurs in the magnetic force flux passing through the first slide member 141.

Due to such a change in the magnetic force flux, induced electromotive force having a direction opposite to the movement direction is generated in the first slide member 141, and the induced electromotive force prevents the relative movement of the first slide member 141. As such, the reduction unit decreases the relative moving speed between the first and second slide members 141 and 142.
