うことができる。The above object can be attained by a pillar having the structure described in the claims. That is, according to the pillar described in claim 1, the outer cylinder and the inner cylinder are provided in one of the plurality of engagement recesses provided in one of the outer cylinder and the inner cylinder. The outer cylinder and the inner cylinder are positioned by a positioning mechanism in which the engagement projection provided on the other cylinder selectively engages using elasticity. Therefore, when adjusting the length by the positioning mechanism, it is possible to save the trouble of removing and screwing the screw member and the trouble of holding the outer cylinder and the inner cylinder at a desired adjustment position. Easy to do.

ることが可能になる。According to the second aspect of the present invention, since the plurality of engaging concave portions are arranged on the outer cylinder and the engaging convex portions are arranged on the inner cylinder, the positioning mechanism can be compactly provided. . Specifically, for example, when the engaging protrusion is disposed on the outer cylinder, an elastic member or the like that imparts elasticity to the engaging protrusion may protrude outside the outer cylinder from the fitting relationship between the outer cylinder and the inner cylinder. Therefore, it is difficult to provide a compact positioning mechanism. On the other hand, in the case where the engaging projection is disposed in the inner cylinder, the elastic member and the like can be built in the inner cylinder, so that the positioning mechanism can be provided in a compact manner.

ることを防止できる。According to the third aspect of the present invention, the plurality of engagement recesses are formed by the through holes in the side wall of the outer cylinder, so that the engagement protrusions are formed from the outside of the outer cylinder. It can be pushed with a fingertip or the like. Therefore, the engagement with the engagement hole can be easily released by pushing the engagement protrusion. In addition, the engagement amount of the engagement protrusion with respect to the engagement hole can be increased, and by the external force on the outer cylinder and the inner cylinder,
It is possible to prevent the engagement between the engagement concave portion and the engagement convex portion from being unnecessarily released. More specifically, for example, when the engagement of the engagement projection with the engagement recess is to be released only by expansion and contraction of the outer cylinder and the inner cylinder, the engagement between the engagement recess and the engagement projection is inevitable. Since the outer cylinder and the inner cylinder must be loosened, the engagement between the engaging concave portion and the engaging convex portion may be unnecessarily released by an external force applied to the outer cylinder and the inner cylinder. On the other hand, when the engagement with the engagement hole is released by pushing the engagement protrusion,
As described above, by increasing the amount of engagement of the engagement convex portion with the engagement hole, external force on the outer cylinder and the inner cylinder makes it unnecessary to engage the engagement concave portion with the engagement convex portion. Release can be prevented.

くて済む。Further, according to the pillar according to the fourth aspect, the elastic member for imparting elasticity to the engaging projection is supported on the inner cylinder by the support member, so that the elastic member can be prevented from falling off. . Further, since the spacer portion of the support member is slidably abutted on the outer cylinder, it is possible to prevent rattling between the outer cylinder and the inner cylinder. Also, there is no need to provide a dedicated component to prevent rattling between the outer cylinder and the inner cylinder.

Therefore, the elastic deformation of the coil spring and the engagement operation and the engagement release operation of the engagement convex portion are performed accurately. In addition, since the coil spring is supported on the inner cylinder by the support member, it is possible to prevent the coil spring from falling off and to prevent the collar member and the engaging projection from falling off. In addition, it is not necessary to provide a dedicated component to prevent the collar member and the engaging projection from falling off.

（図１及び図２参照）。In the pillar 1 configured as described above,
To adjust the length, after removing the screw member 8, push the pin portion 3a of the engaging pin 3 by using the elasticity of the coil spring 4 in the same manner as described above (see the two-dot chain line in FIG. 2). The outer cylinder 10 and the inner cylinder 20 are expanded and contracted. At this time, since the pin portion 3a of the engaging pin 3 is formed in a substantially hemispherical shape, if the pin portion 3a of the engaging pin 3 is pushed in about half, the outer cylinder 10 and the inner cylinder 20 expand and contract. As a result, the pin portion 3a is pushed in while sliding along the edge of the engaging hole 12 of the outer cylinder 10, so that the pushing amount of the pin portion 3a of the engaging pin 3 can be reduced. Further, since the pin portion 3a of the pushed-in engagement pin 3 makes point contact with the side wall 10a of the outer cylinder 10, the friction involved in the expansion and contraction of the outer cylinder 10 and the inner cylinder 20 can be reduced. When the pin portion 3a of the engaging pin 3 faces one of the engaging holes 12 of the outer cylinder 10, the engaging pin 3 is pushed out by utilizing the elasticity of the coil spring 4, and the pin of the engaging pin 3 The portion 3a selectively engages with the engagement hole 12 of the outer cylinder 10 (see FIGS. 1 and 2).

止できる。Further, by forming a plurality of engagement recesses corresponding to the engagement pins 3 of the positioning mechanism 2 with the engagement holes 12 penetrating through the side wall 10a of the outer cylinder 10, the engagement pins 3 (more specifically, The pin portion 3a) can be pushed in from the outside of the outer cylinder 10 with a fingertip or the like. Therefore, the engagement with the engagement hole 12 can be easily released by pushing the engagement pin 3. Further, the engagement amount of the engagement pin 3 with the engagement hole 12 can be increased, and the engagement between the engagement hole 12 and the engagement pin 3 is unnecessarily released by the external force on the outer cylinder 10 and the inner cylinder 20. Can be prevented. More specifically, for example, the engagement of the engagement pin 3 with the engagement hole 12 is performed between the outer cylinder 10 and the inner cylinder 2.
If the engagement is to be released only by the expansion and contraction of 0, the engagement between the engagement concave portion and the engagement pin 3 must be loosened. There is a possibility that the engagement between the engagement recess and the engagement pin 3 is unnecessarily released. On the other hand, when the engagement with the engagement hole 12 is released by pushing the engagement pin 3, as described above, the engagement projection (specifically, the pin portion 3 a) with the engagement hole 12 is released. By making the engagement amount large, it is possible to prevent the engagement between the engagement hole 12 and the engagement pin 3 from being unnecessarily released by the external force on the outer cylinder 10 and the inner cylinder 20.
