Then, toilet seat cover automatic switch device 130 is described.Because toilet seat cover is identical with part formation, the assembly program of automatic switch device 30 with the closet seat with automatic switch device 130, so except following difference, omit its explanation.
The closet seat is that symmetrical part constitutes with automatic switch device 30 and toilet seat cover with automatic switch device 130.As Figure 22, Figure 24 and shown in Figure 28, on the output shaft 140 of toilet seat cover, be provided with rotating shaft 50 insertions are fixed as the roughly OBL connect apertures 141 that can not rotate with automatic switch device 130.And, on the shell 131a of toilet seat cover, be provided with the sidewall 11b that is used for shell 11 integratedly and keep the 131b of hub portion and the bearing of cap assembly 11d of predetermined space to use projection 131c with automatic switch device 130.
Then, for auxiliary unit 80, use Figure 23, Figure 29 explanation.Auxiliary unit 80 is by the connection shaft 81 that can not link rotationally on the rotating shaft 40 of automatic switch device 30, and for closet seat 12 is made an end 82a be fixed in secondary spring 82 on the connection shaft 81 towards opening the direction application of force, and be fixed with the other end 82b of secondary spring 82 and can not be attached at binding lid 83 on the shell 11 rotationally, and cover 83 lids 84 that surround secondary spring 82 with linking, and with the charge and discharge operations bar 85 of closet seat 12 from shell 11 loading and unloading usefulness, and be used for the institutes such as fixed part 86 that auxiliary unit 80 is fixed on the closet seat 12 are constituted.
Form serration at the first end 81a of connection shaft 81 (back shaft of toilet seat cover 13), on the substantial middle part, be formed for limiting the large-diameter portion 81b that connection shaft 81 moves to the axial force direction.And, be formed for and lid 84 inner cylinder portion 84a between the O shape annular groove 81c that seals, and large-diameter portion 81b and O shape annular groove 81c between be formed for the patchhole 81d that an end inserts secondary spring 82.And, be formed for and lid 83 inner cylinder portion 83a between the O shape annular groove 81e that seals, part forms the groove 81f with the roughly the same shape of profile of rotating shaft 40 endways.
One end 82a of secondary spring 82 is towards central authorities bendings, inserts patchhole 81d, and other end 82b is fixed on towards central authorities' bending and is formed among the support slot 83b that links the periphery of covering 83 inner cylinder portion 83a.In addition, the root portion of support slot 83b increase the wall thickness of bottom 83c slightly and form the other end 82b that prevents secondary spring 82 rotation prevent wall 83d.
And, cover 83 rear end linking, form with at the restriction projection 83e that the closet seat is chimeric with the integrally formed engaging protrusion 31q of the peripheral shell 31a of automatic switch device 30 and restriction is rotated, form the retainer 83f of the rotation of restriction charge and discharge operations bar at a place of the peripheral part of the 83e of restriction projection.And, on the 83g of urceolus portion, form variation in diameter small diameter part 83h.Cover 83 openend linking, to make welding be formed at whole circumference with rib 83i, by ultrasonic fusing etc. make cover 84 integrated.
Charge and discharge operations bar 85 is formed with cylinder 85b by the loading and unloading of otch by the support cylinder 85a of otch and below by the top, is formed with the cyclic rib 85c that the inboard and the outside have increased some thickness betwixt.The internal diameter of this cyclic rib 85c and the roughly the same footpath of small diameter part 83h and littler than the 83g of urceolus portion.And, on loading and unloading, be formed with to control and use projection 85d with cylinder 85b.
On fixed part 86, form: with the binding of the roughly the same shape of profile of connection shaft 81 binding crank 86c with opening 86a, the projection 86b that is provided at predetermined intervals along periphery in order not to be rotatably fixed to closet seat 12, summary L word shape.And, on binding crank 86c, form: the following hole 86d that fixed screw element is used.The retainer 86e that moves of the axial force direction of restriction auxiliary unit 80 (except fixed part 86 usefulness).
Then, on one side with reference to Figure 29, the assembly program of auxiliary unit 80 is described on one side.
O shape ring is accommodated among O shape annular groove 81c, the 81e of connection shaft 81, one end 82a of secondary spring 82 is inserted among the patchhole 81d of connection shaft 81, other end 82b is sticked in to link covers among 83 the support slot 83b, thereby connection shaft 81 inserted to link cover in 83 the inner cylinder portion 83a, until the end of inner cylinder portion 83a with till spools 81 large-diameter portion 81b docks.Thus, the other end 82b of secondary spring 82 is accommodated to preventing in the wall 83d.
Then, the first end 81a of connection shaft 81 inserted cover in 84 the inner cylinder portion 84a, at the inboard of lid 84 and link under 83 the state of welding of cover with rib 83i butt joint, by making lid carry out ultrasonic vibration with connection shaft 81, secondary spring 82, link cover 83, cover 84 integrated.
Then, though charge and discharge operations bar 85 is inserted the urceolus 83g of portion, but because the 83g of urceolus portion external diameter is bigger than cyclic rib 85c, so if cyclic rib 85c lifts and is inserted into small diameter part 83h with the 83g of urceolus portion always, then link and cover 83 and charge and discharge operations bar 85 formation one, charge and discharge operations bar 85 comes coming off of restrictive axial force direction by 83g of urceolus portion and cyclic rib 85c.Then use in the opening 86a, make auxiliary unit 80 integrated by the binding of connection shaft 81 being inserted fixed part 86.
