The vehicle seat or the like 2 is attached to the body 1 via a bidirectional urging resistance applying member 4 and is movable bidirectionally between the A position and the B position. The side end 11 and the other end 12 are configured to rotate in opposite directions to each other,
Since the one end 11 and the other end 12 are engaged with the engagement protrusions 13 and 14 of the bracket 5 and are stopped from rotating,
From position A (withdrawal position in use) to position C (neutral position)
When the vehicle seat or the like 2 is rotated at a time, the vehicle seat or the like 2
The direction of rotation of the torsion spring 10 and the direction in which the one end 11 of the torsion spring 10 rotates the pin 17 are the same.
Is assisted by the elastic force for rotating the pin 17, and the vehicle seat 2 and the like 2 are slightly rotated about the rotation shaft 3.

The rotation shaft 3 rotates the pin 17 by the rotation of the vehicle seat 2 and the pin 17 contacts the other end 12 to rotate it. Since the direction is a direction in which the other end 12 of the torsion spring 10 is separated from the other end engaging projection 14, the rotation direction of the pin 17 is opposite to the direction in which the elastic force of the other end 12 acts.
The elasticity of the other end 12 of the torsion spring 10 acts as a resistance, and slowly rotates the vehicle seat 2 or the like 2 to the position B (storage position).

Since the rotation direction of the vehicle seat 2 or the like 2 coincides with the direction in which the other end 12 of the torsion spring 10 rotates the pin 17,
The other end 12 of the torsion spring 10 is assisted by the resilience to return to the original position and reaches the C position (neutral position) lightly, and when passing through the C position (neutral position), the torsion spring 10 The direction in which one side end 11 of the torsion spring 10 is engaged with the one side end engaging projection 13 and the direction of rotation of the vehicle seat 2 are opposite to each other. The elasticity of the side end portion 11 causes resistance, and slowly rotates the vehicle seat or the like 2 to the A position.

の作用を奏する。As described above, the torsion spring 10 is configured such that the one end 11 and the other end 12 are engaged with the one end engagement projection 13 and the other end engagement projection 14 of the bracket 5. Since the elasticity is always applied, there is an opposing two-sided operation when assisting the vehicle in the direction of rotation of the vehicle seat or the like 2 and when opposing resistance.

The elasticity of the parts 12 acts on the rotation of the pin 17 independently without interfering with each other.

を奏する。According to the present invention, the vehicle seat 2 and the like are provided at a fixed position.
In the one storage position around the intake with shaft 3 which is provided to the dynamic between times of the other drawn-out position, the torsion spring 10 provided around the attachment shaft 3, the torsion spring
10 has one side end 11 and the other side end 12, one side end
11 and the other end 12 are both in the storage position and the pull position.
At the neutral position between the extended positions, no elasticity acts, and when the vehicle seat 2 or the like rotates beyond the neutral position to the storage position or the withdrawn position, it engages with a part of the vehicle seat 2 or the like and
The elasticity is accumulated by the rotation operation, and the accumulated elasticity is
Move the vehicle system from the storage position or the withdrawn position to the neutral position.
To assist in the movement of the port 2 etc.
Acts as a resistance when pivoted to the retracted or extended position
So that each of the one end 11 and the other end 12 rotates
Because it is a shock absorber at the time of retracting and retracting the vehicle seat etc. configured to act in the opposite direction depending on the direction ,
When the vehicle seat or the like 2 is rotated from the pulled-out position or the storage position to the intermediate position in the use state, the torsion spring 10 can be operated lightly with the aid of the elasticity of returning to the intermediate position, and can pass through the intermediate position and be pulled out. Up to the storage position, the elasticity of the torsion spring 10 is accumulated, and the vehicle can be slowly rotated with resistance to the rotation of the vehicle seat 2 or the like. Therefore, the torsion spring 10 exerts opposing actions of assistance and resistance depending on the rotation direction of the vehicle seat 2 or the like.
