In the bottom of retainer main body 152, through shape ground is formed with circular patchhole 161.The end (hereinafter sometimes referred to insertion section 170) in the downstream of above-mentioned axle 24 can be inserted in patchhole 161.Be formed with annular groove 171 to outer peripheral face upper annular in insertion section 170.
Lock assembly 153 is configured to, and using synthetic resin as raw material, has formed button portion (link and remove operating portion) 182 and spring (displacement force generating unit) 183 for flat lock main body 181.
Lock main body 181 reciprocatingly can be arranged on the bottom of retainer main body 152 with predetermined stroke.In lock main body 181, on the position almost corresponding with above-mentioned patchhole 161, through shape ground is formed with lockhole 184.The circumference of lockhole 184 can be inserted into the inside of annular groove 171, and this annular groove 171 is formed on the insertion section 170 of axle 24.
Button portion 182 and spring 183 are all configured to the rib vertically erected from the upper surface (stream side surface) near the length direction end of lock main body 181.The surface of button portion 182 is exposed to outside, and operating personnel can make lock assembly 153 slide by this button portion 182 of pressing.Spring 183 is formed as plastic rib, and this rib is formed as some thin wall shapes.By applying the power in laterally (direction vertical relative to fibre bundle moving direction) to the upper end of spring 183, spring 183 elastic deformation can be made.The upper end (upstream-side-end) of spring 183 contacts the outer peripheral face of retainer main body 152.
Under the state being assembled in retainer main body 152 by lock assembly 153, the upper end of spring 183 is kept the outer peripheral face of device main body 152 to the A direction pressing in Fig. 3 and Fig. 4, spring 183 elastic deformation thus.Thus, in spring 183, produce elastic recovering force, this elastic recovering force act as the applying power making lock assembly 153 to the movement of arrow A direction.This applying power is used as return force when operating personnel have pressed button portion 182.This applying power is also used as making the leading section 30 of axle 24 to the power (detailed content is by aftermentioned) of side displacement.
Then, center roller 24 is described to the installation exercise of retainer annex 151.When installing axle 24 to retainer annex 151, first operating personnel make axle arm 92 rotate, and make this axle arm 92 become the state left from nozzle supporting arm 91.Then, operating personnel press with finger button portion 182 and lock assembly 153 are moved to the direction contrary with arrow A, make the edge of the lockhole 184 be formed in lock main body 181 become not outstanding from the inwall of patchhole 161 state.Then, operating personnel keep the state pressing with finger button portion 182, inserted the insertion section 170 of axle 24, and support rubber 65 is inserted into the inside of housing recess 160 from top (upstream side) to patchhole 161 and lockhole 184.
In addition, in this operation, need positively to be pressed into support rubber 65, the first ring portion 66, second ring portion 67 had to make support rubber 65 and the 3rd ring portion 68 are all reliably close to the internal face of housing recess 160.But, in support rubber 65, between the first ring portion 66 and two ring portions 67, be formed with annular groove, the contact area between the internal face of therefore support rubber 65 and housing recess 160 reduces respective amount significantly, and support rubber 65 becomes easy relative to the plug of housing recess 160.
Afterwards, when operating personnel make finger leave from button portion 182, by the recuperability of spring 183, lock assembly 153 moves to arrow A direction, and the edge being formed in the lockhole 184 in lock main body 181 is given prominence to from the inwall of patchhole 161, and enters in the annular groove 171 be formed on insertion section 170.
So, the state shown in Fig. 5 is realized.In this condition, axle 24 is mechanically linked relative to retainer main body 152 by lock assembly 153, even if therefore such as will by axle 24 upwards (upstream side) drawing, this axle 24 also can not depart from from retainer main body 152.
But the internal diameter being formed in the patchhole 161 in retainer main body 152 is formed as, more some greatly than the external diameter of the end of downstream side (insertion section 170) of the axle 24 of this patchhole 161 of insertion, guarantee the end-play to a certain degree of axle 24.The width being formed in the annular groove 171 on insertion section 170 is formed as, more some greatly than the thickness of the lock main body 181 inserting this annular groove 171, also guarantees axial play.Further, the support rubber 65 of the ring-type between retainer main body 152 and axle 24 is configured in, can suitably elastic deformation.
Therefore, as shown in Figure 5, even if under the state that axle 24 is arranged on retainer annex 151 (leading section of axle arm 92), this axle 24 neither be restrained (location) completely, and can carry out moving (more loose restrains) relative to retainer main body 152 in the scope of above-mentioned play.That is, axle 24 is, although be some strokes, except allowing to move diametrically and be mobile in the axial direction, can also carry out making axle to tilt such movement.With this, the leading section 30 of axle 24 also can carry out moving or making towards inclination in certain scope.
In addition, when axle 24 moves as described above, be configured in the support rubber 65 between axle 24 and retainer main body 152, elastic deformation corresponding thereto, produce the mobile recuperability resetted making this axle 24.Specifically, when radially (with the direction that the moving direction of fibre bundle 8 is roughly orthogonal) is mobile for axle 24, mainly the first ring portion 66 and the second ring portion 67 produce and make this move the elastic force of reset, when (with the direction that the moving direction of fibre bundle 8 is almost parallel) is mobile vertically for axle 24, mainly the 3rd ring portion 68 produces and makes this move the elastic force of reset.By the flexible mobile restriction effect of this support rubber 65, under the state that center roller 24 does not apply any power, this axle 24 is maintained on the position almost consistent with the axle center of the housing recess 160 of retainer main body 152, axle center.
On the other hand, even if under axle 24 is as shown in Figure 5 installed on retainer annex 151 state, the elastic deformation of the spring 183 of lock assembly 153 is not also removed completely.That is, the elastic recovering force of this spring 183 does not lose.Because lock main body 181 is stretched by the elastic recovering force of spring 183, the inner peripheral surface that therefore base end part of axle 24 is formed on the lockhole 184 in above-mentioned lock main body 181 presses to arrow A direction.That is, under the state of Fig. 5, the elastic recovering force of spring 183 is used for the insertion section 170 of axle 24 as the masterpiece in arrow A direction.Therefore, axle 24 for fulcrum tilts as seesaw, makes this leading section 30 towards the some distances of direction displacement of the thick-line arrow of Fig. 5 with its axial pars intermedia (being configured with the vicinity of the position of support rubber 65).So, spring 183 has the function of leading section 30 to the power of prescribed direction displacement produced for making axle 24.
By the power that above-mentioned spring 183 produces, the position stability of the leading section 30 of axle 24 effectively can be made.That is, suppose when making this spring force not act on axle 24 completely, this axle 24 such as offsets etc. due to the impact of vibration etc., and the position of leading section 30 likely becomes unstable.In addition, although can the skew of axle 24 that cause such as damping vibration to a certain extent by above-mentioned support rubber 65, but be difficult to prevent the trickle skew of the axle 24 in the scope of support rubber 65 elastic deformation hardly.On the other hand, in the present embodiment, press axle 24 all the time to make its leading section 30 to prescribed direction displacement by the power of spring 183, the power of spring 183 towards almost certain with size.Therefore, retainer main body 152 effectively suppresses the skew of axle 24, the leading section 30 of axle 24 extremely stably can be remained on carried out displacement position on.
