Lock main body 181 can reciprocatingly be arranged on the bottom of keeper main body 152 with predetermined stroke.In lock main body On 181, on the position the most corresponding with above-mentioned insertion hole 161, it is formed with lockhole 184 through shape.The circumference of lockhole 184 Being inserted into the inside of annular groove 171, this annular groove 171 is formed on the insertion section 170 of mandrel 24.

Button portion 182 and spring 183 be all configured to from lock main body 181 length direction end near upper surface ( Trip side surface) rib that vertically erects.The surface of button portion 182 is exposed to outside, and operator are by pressing this button portion 182 Lock assembly 153 can be made to slide.Spring 183 is formed as plastic rib, and this ribbed becomes some thin wall shapes.By right The upper end of spring 183 applies the power in laterally (direction vertical relative to fibre bundle moving direction), it is possible to make spring 183 Elastic deformation.The outer peripheral face of upper end (upstream-side-end) the contact keeper main body 152 of spring 183.

When being assembled in keeper main body 152 by lock assembly 153, the upper end of spring 183 is kept device The periphery of main body 152 presses towards the A direction in Fig. 3 and Fig. 4, thus spring 183 elastic deformation.Thus, in spring 183 Middle generation elastic recovering force, this elastic recovering force act as the applying power making lock assembly 153 move to arrow A direction.This applying Power is used as return force when operator have pressed button portion 182.This applying power is also act as making mandrel 24 Leading section 30 is to the power (detailed content is by aftermentioned) of side displacement.

Then, center roller 24 illustrates to the installation exercise of keeper adnexa 151.Installing to keeper adnexa 151 In the case of mandrel 24, first operator make mandrel arm 92 rotate, and make this mandrel arm 92 become and prop up gripping arm 91 from nozzle and leave State.Then, operator press with finger button portion 182 and make lock assembly 153 move to the direction contrary with arrow A, The edge being formed at the lockhole 184 in lock main body 181 is made to become the state not highlighted from the inwall inserting hole 161.Then, operation Personnel keep the state pressing with finger button portion 182, by the insertion section 170 of mandrel 24 from top (upstream side) to inserting hole 161 and lockhole 184 insert, and support rubber 65 is inserted into the inside of housing recess 160.

It addition, in this operation, need positively to be pressed into support rubber 65, so that the first ring that support rubber 65 is had Portion's the 66, second ring portion 67 and the 3rd ring portion 68 the most reliably internal face with housing recess 160 is close to.But, at support rubber In 65, between the first ring portion 66 and two ring portions 67, it is formed with annular groove, therefore support rubber 65 and the internal face of housing recess 160 Between contact area reduce respective amount significantly, support rubber 65 becomes easy relative to the plug of housing recess 160.

Afterwards, when operator make finger leave from button portion 182, the lock assembly by the recuperability of spring 183 153 move to arrow A direction, and the edge being formed at the lockhole 184 in lock main body 181 highlights from the inwall inserting hole 161, and enters Enter to be formed in the annular groove 171 on insertion section 170.

So, it is achieved the state shown in Fig. 5.In this condition, mandrel 24 by lock assembly 153 relative to keeper master Body 152 mechanically links, even if the most such as will also will not be from keeper by mandrel 24 upwards (upstream side) drawing, this mandrel 24 Main body 152 departs from.

But, the internal diameter inserting hole 161 being formed in keeper main body 152 is formed as, and ratio inserts this insertion hole 161 The external diameter of the end of downstream side (insertion section 170) of mandrel 24 is the most some, it is ensured that the end-play to a certain degree of mandrel 24.Formed The width of the annular groove 171 on insertion section 170 is formed as, more some, also than the thickness of the lock main body 181 inserting this annular groove 171 Guarantee axial play.Further, the ring-type support rubber 65 being arranged between keeper main body 152 and mandrel 24, it is possible to suitable Work as elastic deformation.

Therefore, even if as it is shown in figure 5, being arranged on keeper adnexa 151 (leading section of mandrel arm 92) in mandrel 24 Under state, this mandrel 24 is not to be restrained (location) completely, and can be relative to keeper master in the range of above-mentioned play Body 152 moves (more loose restrains).That is, mandrel 24 is, although be some strokes, but except allowing to move diametrically And outside mobile in the axial direction, additionally it is possible to carry out making axle tilt such mobile.As it does so, the leading section 30 of mandrel 24 also is able to Move in certain scope or make towards inclination.

It addition, when mandrel 24 moves as described above, the supporting rubber being arranged between mandrel 24 and keeper main body 152 Glue 65, corresponding thereto elastic deformation, produce the recuperability of the mobile reset making this mandrel 24.Specifically, in mandrel 24 When radially (direction being substantially orthogonal with the moving direction of fibre bundle 8) is mobile, the mainly first ring portion 66 and the second ring portion 67 Producing makes this move the elastic force of reset, moves (with the direction lain substantially parallel to the direction of movement of fibre bundle 8) vertically in mandrel 24 Time dynamic, the mainly the 3rd ring portion 68 produces and makes this move the elastic force of reset.By the elastic movement of this support rubber 65 Restriction effect, when center roller 24 does not applies any power, this mandrel 24 is maintained at axle center and keeper main body 152 On the position that the axle center of housing recess 160 is the most consistent.
