The second shape memory draft helical spring 135, the 136 and second common draft helical spring 130,131 are described in detail.As shown in figure 13, the second shape memory draft helical spring 135, the 136 and second common draft helical spring 130,131 equal overlength be formed on the second moving-member 140 vertically on.Here, as shown in figure 13, be formed with two front sides hooks 143,144 the leading section (bottom among Figure 13) of the second moving-member 140 is forwards outstanding, this front side hook 143,144 the second moving-member 140 vertically on the interval arrange.Passing through respectively longitudinally on above-mentioned front side hook 143,144, an end (left part) links each second shape memory draft helical spring 135,136.Each second shape memory draft helical spring 135, longitudinally the other end (right part) of 136 are separately installed with pin 135a, the 136a that vertically is located at above the second driving mechanism installing component 120.In addition, as shown in figure 13, be formed with two rear sides hooks 145,146 the rearward end (upper end among Figure 13) of the second moving-member 140 is rearward outstanding, this rear side hook 145,146 the second moving-member 140 vertically on the interval arrange.Passing through respectively longitudinally on above-mentioned rear side hook 145,146, an end (right part) links each second common draft helical spring 130,131.Each second common draft helical spring 130, longitudinally the other end (left part) of 131 are separately installed with pin 130a, the 131a that vertically is located at above the second driving mechanism installing component 120.Irrelevant with the environment for use temperature, each second common draft helical spring 130,131 is given and active force to a direction of its vibration-direction (left among Figure 13 to) the second moving-member 140 usually.

Here, the second shape memory draft helical spring 135,136, raise and reach in the situation of the 3rd temperature (transient point) from the temperature cause temperature below the 4th temperature in the environment for use temperature, present martensite metamorphosis, return to the shape (spring 135,136 shapes of shrinking) of memory, thereby the elastic force of anti-the second common draft helical spring 130,131 active forces can occur.This elastic force (N) be towards with the second common draft helical spring 130,131 active force (N) power of direction (right among Figure 13) antithesis, irrelevant with the second common draft helical spring 130,131 contemplated elongations, be set as the power larger than this active force absolute value.And the second shape memory draft helical spring 135,136 makes the second moving-member 140 mobile to the opposite side (right among Figure 13) of vibration-direction under the state of the second tooth bar 141 and pinion 14b engagement by this elastic force.And among the pinion 14b on being engaged to the second tooth bar 141, this moving rotating is changed to dextrorotary revolving force, and the second driving force when raising as temperature is given and rotated display unit 10.Accordingly, rotate display unit 10 to right rotation, make it from the front state of the rising of the temperature shown in Figure 13 (b), the state displacement after raising to the temperature shown in Figure 13 (c).And, under the state of Figure 13 (b), shown in Fig. 9 (b), to rotate display unit 10 and be positioned on the first turned position, described the first turned position is to make to travel to notice that (11A～11D) is positioned at the position on the display position to identified surface 11; Under the state of Figure 13 (c), shown in Fig. 9 (c), to rotate display unit 10 and be positioned on the 3rd turned position, described the 3rd turned position is to make heatstroke notice that (13A～13D) is positioned at the position on the display position to identified surface 13.Namely, based on present embodiment, in the situation that the temperature that occurs reaching the 3rd temperature from the temperature below the 4th temperature raises, by to rotate display unit 10 when raising with temperature from the first turned position to the second driving force of the 3rd turned position displacement, thereby can carry out noting from travelling that (11A～11D) notes identified surface 13 (the switching demonstration of 13A～13D) to heatstroke to identified surface 11.

On the other hand, the second shape memory draft helical spring 135,136, reduce and reach in the situation of the 4th temperature from the temperature cause temperature more than the 3rd temperature in the environment for use temperature, lose the elastic force (shape memory effect) of anti-the second common draft helical spring 130,131 active forces.Accordingly, the second moving-member 140 is by the second common draft helical spring 130,131 active force, under the state of the second tooth bar 141 and pinion 14b engagement, allows the side (left among Figure 13 to) to vibration-direction mobile.And among the pinion 14b on being engaged to the second tooth bar 141, this moving rotating is changed to the revolving force to anticlockwise, and the second driving force when reducing as temperature is given and rotated display unit 10.Accordingly, rotate display unit 10 to anticlockwise, make it reduce front state from the temperature shown in Figure 13 (c), Fig. 9 (c), the state displacement after reducing to the temperature shown in Figure 13 (b), Fig. 9 (b).Namely, based on present embodiment, occurring in the situation about from the temperature more than the 3rd temperature, reducing to the temperature below the 4th temperature, by to rotate display unit 10 when reducing with temperature from the 3rd turned position to the second driving force of the first turned position displacement, thereby can carry out noticing that from heatstroke (13A～13D) notes identified surface 11 (the switching demonstration of 11A～11D) to identified surface 13 to travelling.

And, as the 3rd temperature, notice that from expression heatstroke (viewpoint of 13A～13D) wishes to adopt the temperature (for example, can be 31 ℃) that begins to be considered as high temperature as outside atmosphere to identified surface 13.In addition, as the 4th temperature, adopt the temperature (for example, only reducing the temperature (can be 24 ℃) of set point of temperature from the 3rd temperature) that is determined by the second shape memory draft helical spring 135,136 temperature hysteresis.And then, as the second shape memory draft helical spring 135,136 material, can adopt Ni-Ti to be associated gold etc., present the marmem of desired characteristic (transient point, temperature hysteresis etc.).In addition, as the second common draft helical spring 130,131 material, can use generally well-known spring material.

But, shown in Figure 13 (c), pinion 14b with the state of the second tooth bar 141 engagement under, by move to locational the first par 47 of pinion 14b along with moving of the first moving-member 40, can remove and the engagement of the first tooth bar 41.In addition, shown in Figure 13 (a), pinion 14b with the state of the first tooth bar 41 engagement under, by move to locational the second par 147 of pinion 14b along with moving of the second moving-member 140, can remove and the engagement of the second tooth bar 141.Accordingly, can prevent to rotate display unit 10 to and First Driving Force with to and the second driving force between conflict so that suitable rotation of rotating display unit 10 and respectively note identified surface 11,12,13 switching demonstration with it.

But, shown in Figure 13 (b), note under the show state of identified surface 11 travelling, both all move to the first par 47 and the second par 147 on the position of pinion 14b, thereby pinion 14b and the first tooth bar 41 and both engagements of the second tooth bar 141 are all removed.In this case, notice that as being used for keeping travelling identified surface 11 is positioned on the display position (namely, the first turned position) accessory (parts beyond the shape memory draft helical spring), owing to can not use the engagement of gear (tooth bar, pinion), wishing to seek miscellaneous part.

Therefore, have in the present embodiment the attitude of rotation accessory, it utilizes the magnetic force auxiliary rotary display unit 10 of permanent magnet to the rotation attitude of the first turned position.Specifically, in the present embodiment, at least one of upper part 15 and lower member 14, it forms by kicker magnets such as iron with attention identified surface 11 apex portion in opposite directions of travelling at least.In addition, in the present embodiment, as shown in figure 14, equipped with permanent magnetism iron 50 on the immediate position of kicker magnet part of the upper part 15 of backboard section 4c inboard and/or lower member 14.The rotatable parts 10 that can will turn on the first turned position by the magnetic force of permanent magnet 50 accordingly, stably remain on the first turned position.And, replace permanent magnet 50, the embeded slot structure can also be set, this embeded slot structure is fitted on the approximated position of the 4c of backboard section the apex portion of upper part 15 and/or lower member 14.In this case, also can by the latching force of embeded slot structure, will rotate display unit 10 and stably remain on the first turned position.But keeping the confining force (magnetic force or latching force) of rotation display unit 10 by rotation attitude accessory is the power of following degree, and it does not hinder pinion 14b and arbitrarily tooth bar 41,141 the rear moving-member 40 of engagement recovery, 140 movement.
