A bearing 4 such as a bearing pivotally supported around the shaft axis L, a resin rotating member 2 attached to an outer peripheral surface (outer ring) 42 of the bearing 4, and an inner peripheral surface (inner ring) of the bearing 4 A resin-made support member 5 having a shaft portion 51 to be inserted into 41 in a front protruding shape and a male screw portion 52 in a rear protruding shape, and a cap-type resin made to be screwed into the male screw portion 52 of the support member 5 Pressing member 6.

As shown in FIGS. 1 and 2, the support member 5 is made of a resin-made support body member 31 having a shaft portion 51 and a male screw portion 52, and prevents the bearing 4 from slipping forward by being fixed to the shaft portion 51. And a retaining member 32. That is, the bearing 4 (the inner ring 41 thereof) is sandwiched between the flange portion 59 of the retaining member 32 and the stepped surface of the shaft portion 51 of the support body member 31, and is fixed to the shaft portion 51 in an outer fitting shape. Yes.
The rotating member 2 has a circular cylindrical shape, and the bearing 4 (the outer ring 42) is press-fitted therein. In other words, the rotating member 2 is fixed to the outer peripheral surface (outer ring) 42 of the bearing 4 in an outer fitting shape.

  That is, the rotating member 2 is attached to the shaft portion 51 of the supporting member 5 via the bearing 4 so as to be fitted outside, so that the rotating member 2 can rotate about the horizontal axis L with respect to the supporting member 5. The support member 5, the bearing 4, and the rotation member 2 are configured as one rotation support unit Y.

  As shown in FIGS. 1, 3, and 4, the rotation support unit Y is attached to the back wall portion 12 of the wheel body 1. In the unit assembly state in which the rotating member 2 is attached to the wheel main body 1, the wheel main body 1 can rotate about the horizontal axis L with respect to the support member 5.

As shown in FIG. 1, the rotation support unit Y is attached to the back surface 12 b side of the back wall portion 12 of the wheel body 1 and is attached so as not to penetrate the back wall portion 12.
In other words, the rotating member 2, the support member 5, and the bearing 4 are attached to the back surface 12b side of the back wall portion 12, and in the assembled state (use state), the front surface 12a side (inside the wheel) of the wheel body 1 Are attached so as not to form a protruding portion (protruding portion) protruding forward.

  Then, as shown in FIG. 4, a fixing member K such as a stand member is disposed between the supporting member 5 and the pressing member 6, and the pressing member 6 is screwed into the male screw portion 52 of the supporting member 5. The support member 5 is attached (fixed) to the fixing member K by clamping the support member 5 and the pressing member 6 by screwing. The fixing member K is not limited to the wire-type stand shown in the figure, and can be an L-shaped stand, a wire net for a breeding gauge, or the like.

  As shown in FIG. 1, the bearing 4 can be disposed close to the back wall portion 12 of the wheel body 1, and the back wall portion 12 of the wheel body 1 is supported from the back surface 12 b side by the front end surface of the rotating member 2. First, the force from the wheel main body 1 acts on the outer peripheral surface (outer ring) 42 of the bearing 4, and the load F from the small animal related to the wheel main body 1 and the forward / backward deflection acting on the wheel main body 1 (see arrow W). ).

Further, as shown in FIGS. 1 and 5A, the surface 12a of the back wall portion 12 of the wheel body 1 is formed in a smooth surface shape (vertical flat surface shape) having no convex portions.
For example, in the prior art shown in FIG. 11, since the concave portion 92e into which the intermediate portion of the shaft member 93 is inserted is formed on the back surface 92b of the back wall portion 92, the central portion (horizontal axial center of the display surface 92a is formed. A boss-shaped convex portion 92d is formed around L9, and the back wall portion 92 has a stepped plate shape protruding forward.
However, as shown in FIG. 1 and FIG. 5 (a), the wheel body 1 according to the present invention does not have a protrusion 12 that protrudes forward such as a boss for assembling components on the surface 12a. First, the display surface 12a is straight (vertical line shape) in cross-sectional side view. In other words, the back wall portion 12 has a flat plate shape (not a stepped plate shape protruding forward or a stepped plate shape protruding rearward). Further, in the surface 12a, there is no convex portion in the central region centered on the horizontal axis L. Moreover, the center hole is not formed.

  That is, as shown in FIGS. 1 and 9, the front surface 12a side (inside the wheel) of the wheel body 1 has no front protruding portion (part), and the back wall portion 12 has a forward protruding shape. Because there are no convex parts such as bosses, even if the small animal moves inside the wheel and rotates the wheel body 1, there are no parts or parts that hit the back or flank of the small animal and exercise without stress Can be made. Further, with the wheel main body 1 attached to the fixing member K, the inner peripheral surface of the circumferential wall portion 11 of the wheel main body 1 and the front surface 12a of the back wall portion 12 can be wiped and cleaned easily and quickly.

Next, a unit attaching / detaching structure for detachably attaching the rotation support unit Y to the back surface 12b side of the back wall portion 12 of the wheel body 1 will be described.
As shown in FIGS. 1 to 3 and FIG. 5B, the unit attachment / detachment structure is formed on the back surface 12b of the back wall portion 12 of the wheel body 1 so as to protrude rearward (centering on the horizontal axis L). A plurality of annular protruding wall portions 81, a plurality of locking protrusions 82 that are arranged at equal intervals around the horizontal axis L and project radially inward from the tip of the protruding wall portion 81, and a horizontal axis on the back surface 12b. A plurality of rear protruding tongue pieces 83 arranged at equal intervals around L and small convex portions 84 protruding radially inward from the tongue pieces 83 are provided.

  Further, as shown in FIGS. 1 to 3 and FIG. 6, the unit attaching / detaching structure has an arcuate cage that is disposed at equal intervals around the horizontal axis L at the front edge of the rotating member 2 and protrudes radially outward. -Like locking projection 71, a contact portion 72 arranged at equal intervals around the horizontal axis L in the vicinity of the locking projection 71, and a radially inward position from the outer peripheral wall 20 of the rotating member 2 Are provided with a tongue piece 73 that protrudes forward at equal intervals around the horizontal axis L and is elastically deformable in the radial direction, and a small convex portion 74 that protrudes radially outward from the tongue piece 73. ing.

Here, the unit attachment / detachment structure will be described together with the method for attaching / detaching the rotation support unit Y. For ease of explanation, the case where the wheel body 1 is fixed and the rotating member 2 is operated will be described.
As shown in FIG. 3, the rotating member 2 is brought close to the back surface 12 b of the wheel body 1 along the horizontal axis L, and the rotating member 2 is engaged between the locking protrusions 82 and 82 adjacent in the circumferential direction. The stop piece 71 and the contact portion 72 are disposed, and the rotating member 2 is rotated in one direction around the horizontal axis L. Between the rear surface 12b of the wheel body 1 and the locking projection piece 82, the locking projection piece 71 of the rotating member 2 is disposed, and the contact portion 72 of the rotating member 2 contacts the locking projection piece 82 of the wheel body 1. Thus, the rotation is prevented, and the wheel body 1 and the rotating member 2 are brought into an engaged state in which the separation in the front-rear direction is prevented.

  Further, in the middle of rotating the rotating member 2 in one direction to engage, the small convex portion 74 of the rotating member 2 comes into contact with the small convex portion 84 of the wheel body 1, but gives a predetermined rotational operation force. Thus, the tongue piece 73 of the rotating member 2 is elastically deformed radially inward, and the small convex portion 74 of the rotating member 2 gets over the small convex portion 84 of the wheel body 1 and is locked.

  Even when the rotating member 2 receives an external force that rotates in the other direction (disengagement direction) in the locked state, the small convex portion 74 of the rotating member 2 abuts on the small convex portion 84 of the wheel body 1. The rotation in the unlocking direction is prevented. That is, when the rotating member 2 is rotated in the other direction with a predetermined rotational operation force, the rotation in the disengagement direction becomes possible, the engagement and the lock are released, and the wheel body 1 and the rotation support unit Y are separated. It is possible.

That is, in the unit attachment / detachment structure, the back surface 12b of the wheel body 1 and the rotating member 2 approach each other in the front-rear direction, and the wheel body 1 and the rotating member 2 are relatively different from each other around the horizontal axis L. , The locking protrusions 82 of the wheel body 1 and the locking protrusions 71 of the rotating member 2 engage with each other to prevent the wheel body 1 and the rotating member 2 from separating in the front-rear direction. Engagement means for making the engagement state is provided.
Further, the unit attaching / detaching structure is such that the small convex portion 84 of the wheel body 1 and the small convex portion 74 of the rotating member 2 are in contact with each other when an engagement releasing rotational force less than a predetermined rotational operation force is applied in the engaged state. Locking means for contacting and preventing rotation in the disengagement direction is provided.

  The unit attaching / detaching structure is a structure that does not require other members such as a screw member and a nut member, and a tool, and allows the wheel main body 1 and the rotating member 2 to be attached and detached by the user's hand. Further, since only the wheel main body 1 has to be removed from the rotation support unit Y with the rotation support unit Y attached to the fixing member K during cleaning, it is easy to use and there is a risk of parts being lost. 11 (the conventional technique of FIG. 11 requires the nut member 96 to be removed, which may cause the nut member 96 to be lost). Moreover, since the bearing 4 is not interposed in the removed wheel main body 1, it can be washed with water.

Further, as shown in FIG. 7, the support body member 31 has a cylindrical shaft portion 51 that protrudes forward from the intermediate wall portion 53 having a vertical wall shape, and a male screw portion that protrudes rearward from the intermediate wall portion 53. 52.
The male screw portion 52 is a split screw type divided into four with a cross-shaped slit portion 54. By matching the crossing part of the wire net of the breeding gauge to the center part of the cross-shaped slit part 54 and screwing the pressing member 6 to the male screw part 52, the back surface (pressing surface) of the intermediate wall part 53, The wire net can be held between the front end surface of the pressing member 6 and fixed (attached). By making it correspond to the cross-shaped slit portion 54, the support main body member 31 can be attached while being prevented from being displaced by the wire net in the front-rear and left-right directions and the rotational direction. Note that the support main body member 31 of FIG. 2 is shown in a simplified cross-sectional view in which the cross-shaped slit portion 54 and the die punching hole are omitted.

  Further, an inverted U-shaped groove portion 55 into which an inverted U-shaped upper portion of the wire-type stand is inserted is provided on the back surface of the intermediate wall portion 53 of the support main body member 31. Further, a pair of left and right hook portions 56, 56 that can be suspended on the left and right horizontal upper edges of the wire-type stand are provided in the vicinity of the upper portion of the recessed groove portion 55. The attachment work is facilitated by suspending the upper edge of the wire stand on the hook portion 56.

  Further, as in the other example shown in FIG. 8, the support main body member 31 may have a hanging extension part 53 d that extends downward (toward the left and right) downward on the intermediate wall part 53. good. The hanging extending portion 53d can increase the area of the contact surface or the recessed groove portion 55 that contacts the fixing member K, and stably supports a large wheel body 1 having an outer diameter of 200 mm or more. It becomes possible.

As shown in FIGS. 1 and 2, the retaining member 32 includes an insertion portion 58 that is inserted into the center hole (inner peripheral surface) of the shaft portion 51 of the support main body member 31, and the bearing 4 (the inner ring 41 thereof). ) And a retaining flange 59 for pressing the front end surface.

  In the present invention, the design can be changed, and the unit attaching / detaching structure requires that the rotating member 2, the bearing 4 and the supporting member 5 penetrate the back wall portion 12 of the wheel body 1 (appear from the surface 12a). For example, a detachable structure other than that shown in the drawing may be used (free). For example, the locking protrusions 82 and the small protrusions 84 of the wheel body 1 are provided in a radially outwardly protruding manner, and the rotation member 2 is locked. The projecting piece 71 and the small convex part 74 may be provided in a radially inward projecting shape. Alternatively, the small convex portion 84 of the wheel main body 1 may be provided so as to protrude rearward from the back surface 12b, and the small convex portion 74 of the rotating member 2 may be provided so as to protrude forward from the front end surface so that it can be locked and unlocked. Further, the concave groove portion 55 of the support main body member 31 may be provided in a cross shape so as to correspond to the crossing portion of the wire net of the breeding gauge. The bearing 4 is preferably a rolling bearing such as a ball bearing (in particular, a radial ball bearing having an outer ring and an inner ring), but may be a sliding bearing.

  As described above, the exercise apparatus for small animals of the present invention includes a wheel body 1 having a front opening having a circumferential wall portion 11 and a circular plate-like back wall portion 12, and the wheel body 1 around a horizontal axis L. And a support member 5 having a shaft portion 51 inserted into the inner peripheral surface 41 of the bearing 4, and an outer peripheral surface of the bearing 4. 42, and the support member 5 is attached to the fixed member K. The rotary member 2 is disposed on the back surface 12b side of the back wall portion 12 of the wheel body 1. Since it is attached without penetrating the back wall 12, there is no front protruding part that touches the small animal that rotates the wheel body 1 inside the wheel body, and exercises without causing the small animal to feel stress. In addition, the hair of small animals can be prevented from coming off. In addition, no mischief that causes the front projecting portion to be rolled is generated, and durability can be improved. The inside of the wheel main body 1 attached to the fixing member K such as a wire stand can be easily and hygienically wiped and cleaned.

  In addition, since the surface 12a of the back wall 12 is formed in a smooth surface without a convex portion, the inside of the wheel body 1 (the movement space of the small animal) can be widened, and it can be rubbed by the moving small animal. As you can see, there is no part to touch and you can exercise without feeling stress. It can prevent small animals from being beaten and can improve durability. The front surface 12a can be easily cleaned.

  Further, since the bearing 4, the support member 5, and the rotating member 2 are detachably attached to the wheel body 1 as one rotation support unit Y, the wheel body 1 is attached to the fixing member K (attached). ) Can be performed easily and quickly. There is no risk of parts being lost during attachment work or cleaning work. Only the wheel body 1 can be removed from the fixing member K and washed with water.
