この考案は自転車用ペダル、詳しくは踏面をもったペダ
ルボテ゛イを、自転車のクランクに螺着するペダル軸に
片持状に支持してなる自転車用ペダルに関する。[Detailed Description of the Invention] This invention relates to a bicycle pedal, and more particularly to a bicycle pedal in which a pedal body with a tread surface is supported in a cantilevered manner on a pedal shaft screwed onto the crank of the bicycle.
自転車用ペダルとして、クランクに螺着するペダル軸に
、ペダルボディを偏位させて片持状に支持し、該ボディ
の踏面が常に上方を指向すべくなして、自転車に乗ると
きペダルの踏込操作を行ない易いようにしたものがある
。As bicycle pedals, the pedal body is supported in a cantilevered manner on a pedal shaft that is screwed onto the crank, and the tread surface of the body is always directed upward, so that the pedal can be depressed when riding a bicycle. There are things that make it easier to do.
従来この種ペダルは、クランクに螺着するペダル軸内に
、ペダルボテ゛イの偏位された軸部を差込み、このペダ
ル軸とボテ゛イ軸部の対向面2個所に、それぞれ環状溝

2列の転動体により前記ボディをペダル軸に回転自由に
支持すべくしている。Conventionally, this type of pedal has been designed by inserting the offset shaft portion of the pedal body into the pedal shaft that is screwed onto the crank, and forming annular grooves at two opposing surfaces of the pedal shaft and the body shaft portion, respectively. Rolling elements are held in a row in the annular groove, and the two rows of rolling elements are used to support the body rotatably around the pedal shaft.
従ってこのペダルによれば、ペダル軸内に転動体を設け
る関係上、該ペダル軸の外径が大となって、一般的なり
ランクには取付けることができず、専用のクランクを必
要としたのである。Therefore, according to this pedal, the outer diameter of the pedal shaft is large due to the provision of rolling elements within the pedal shaft, so it cannot be installed on a general rank, and a special crank is required. be.

の強度を低下させる問題点もあった。Moreover, since the pedal body is supported by two rows of rolling elements, the pedal has the disadvantage that the structure is complicated, the assembly work is troublesome, and the pedal is expensive.
In addition, the part of the pedal body that attaches to the crank may bulge outward, causing the part to hit your foot.
Moreover, the bending moment caused by the pedal body when the pedal is depressed increases by the amount of the bulge, which causes a problem of lowering the strength of the crank.
本考案は以上のごとき問題点を解決すべく考案したもの

強度を大ならしめるべくしたのである。The present invention was devised to solve the above problems, and includes a cylindrical boss section on one side of the pedal body, a threaded section on the pedal shaft that is screwed onto the crank, and a mantle on the boss section. A receiving part to be fitted is provided, an annular groove is formed between the boss part and the receiving part, and the rolling elements are held in a line in the annular groove, so that the O-row of rolling elements holds the pedal body. By supporting the pedal body with a row of rolling elements, the pedal structure is simplified and assembly work is facilitated, and the attachment part of the pedal body to the crank is minimized. The small width was designed to prevent this part from coming into contact with the foot, and to reduce the bending moment caused by the body, thereby increasing the strength of the crank.
またペダル軸のクランク側方部に受部を設け、この受部
と前記ボテ゛イのボス部との間に一列の転動体を介在さ

を取付可能となしたのである。In addition, by providing a receiving part on the crank side part of the pedal shaft and supporting the body by interposing a row of rolling elements between this receiving part and the boss part of the body, the threaded part of the pedal shaft can be made larger. There is no need to do so, and the pedal can be attached to a general crank.
次に本考案の自転車用ペダルを図面の実施例によって説

溝17を形成するのである。Thus, an annular body 14 having an inclined surface 13 on the inner end surface is integrally fitted inside the boss portion 9 of the support body 10, and an inclined surface 15 is provided on the inner end surface on the opening side of the boss portion 9. This annular body 14 and the pressing body 16 are screwed together.
The inclined surfaces 13 and 15 form one V-shaped annular groove 17 that faces the annular groove 7 of the receiving portion 6 of the pedal shaft 1.

なすことも可能である。That is, one annular groove 19 having a semicircular arc shape is formed on the inner circumferential surface of the boss portion 9 of the support body 10, while an inclined surface 20 is provided on the outer end surface of the receiving portion 6 of the pedal shaft 1. A tapped hole 21 is formed in the axial center of the pedal shaft 1, and a pressing body 24 is provided in the tapped hole 21, which has an inclined surface 23 that faces the inclined surface 20 and forms a V-shaped annular groove 22. , a large number of rolling elements 18 are threaded through the outer opening 25 of the boss part 9 and are disposed between the annular grooves 19 and 22 formed by the annular groove 19 of the boss part 9 and the pedal shaft 1 and the pressing body 24. It is also possible to charge the pedals in a row and use the row of rolling elements 18 to rotatably support the pedal body 8 on the pedal shaft 1.

の強度を高め得るのである。As explained above, in the bicycle pedal of the present invention, the boss part of the pedal body and the receiving part of the pedal shaft each have IT.
One annular groove is formed, rolling elements are inserted in a row between each annular groove, and the row of rolling elements supports the pedal body freely around the pedal shaft. The structure and assembly work of the pedal body can be simplified, and it can be provided at low cost, and the part where the pedal body is attached to the crank, that is, the part where the body is attached to the crank, that is, the boss part of the body, can be made narrow. The pedal can be rotated smoothly without the foot touching the part when rotating the pedal, and by making the width of the boss part small, the bending moment of the body relative to the crank can be made small. This increases the strength of the crank.
