つて、強制的に弾性線材ａに力が加わり、前記気
筒部片ｃの貫通孔と線接触により弾性線材１ａの
脚部ｂが摺動するものであつた。 As shown in Fig. 4, the locking structure for the elastic wire of the conventional rolling piston type rotary compressor is as follows.
A structure was adopted in which a leg part b extending at right angles is provided at the tip of the elastic wire a, and the leg part b is inserted into the through hole of the cylinder piece c and locked, but as the gate valve d moves back and forth, When a force is applied to the elastic wire a, the leg b of the elastic wire 1a slides due to line contact with the through hole of the cylinder piece c.
そのため、この摺動による摩耗をさけるため
に、貫通孔の径などの精度を仕上げたり、気筒部
片ｃを耐摩耗性を考慮した材質に選定する必要が
あり、高価となるなどの欠点を有していた。 Therefore, in order to avoid wear caused by this sliding, it is necessary to improve the accuracy of the diameter of the through hole, etc., and to select a material for the cylinder part c that takes wear resistance into consideration, which has disadvantages such as being expensive. Was.

を図ることを目的とするものである。 The present invention solves the above-mentioned conventional drawbacks,
It facilitates the insertion of the elastic wire into the support rod, makes it difficult for the elastic wire to come out from the support rod, and
The purpose of this is to increase the pressure-receiving surface by making surface contact with the through-hole of the cylinder piece, thereby improving wear resistance and extending the service life.

A motor stator is fixed inside, 3 is a motor rotor, 4 is a crankshaft fixed to the rotor 3, 5 is a roller into which the crankshaft 4 is fitted, and 6 is a cylinder component. Part of the outer periphery of the cylinder component 6 is provided with a partition plate groove 8 in a penetrating state, into which the partition plate 7 is fitted and slid back and forth. 9 connects the partition plate 7 to the cylinder part 6
One end 9a of this elastic wire 9 is attached to the edge of the partition plate 7, and the other end once extends in the crankshaft direction and is pressed against the roller 5 from the outside. It extends along the outer periphery. Reference numeral 11 denotes a through hole formed in the cylinder component 6, which is in a relationship of approximately 180° with the partition plate groove 8;
Extends in the direction of the crankshaft. Reference numeral 12 denotes a cylindrical support rod made of metal or resin inserted into the through hole 11, and is appropriately prevented from coming off, especially at the lower end at a position at the same height as the extending end of the elastic wire 9. A pore 13 passing through is provided. Here, the other end of the elastic wire 9 is bent at an obtuse angle θ toward the partition plate as shown in FIGS. 2 and 3B,
The leg portion 10 is fitted into the hole 13 of the support rod 12 . In addition, 14 is an upper bearing part.

ない。 In the above configuration, since the leg portion 10 of the elastic wire 9 is inserted into the pore 13 of the support rod 12, the contact area with the through hole 11 of the cylinder component 6 becomes large.
Since force acts on the entire pressure-receiving surface of the leg portion 10, wear resistance is improved. In addition, since the legs 10 of the elastic wire 9 are bent at an obtuse angle toward the partition plate, the support rod 12
It has a structure that prevents it from falling out during exercise due to the set hole 3. That is, as shown in FIG. 3A, the legs 10 are connected to the partition plate 7.
When the support rod 12 is bent in the opposite direction, a force F 2 acts in the direction of the support rod 12 coming out of the assembly hole 13, and the leg portion 10
falls out from the assembly hole 13 of the support rod 12. However, when the partition plate 7 is bent as shown in B in the figure, the force F 1 acts in the direction of inserting the leg 10 into the pore 13, so the leg 10 does not come out of the pore 13.

ど、種々の利点を有するものである。 As is clear from the above embodiments, the partition plate holding device for a rotary compressor according to the present invention absorbs the force applied to the elastic wire due to the reciprocating movement of the partition plate through line contact or surface contact between the support rod and the through hole. It has various advantages, such as improving the wear resistance of the elastic wire and having a simple structure that allows it to be manufactured at a very low cost.
