DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view of a vehicular turning indicator 1 according to the present invention, FIG. 2 is an exploded perspective view of a cancel cam barrel 14 and a cancel cam 20, and FIG. 3 is a cancel cam barrel 31.
4 is an exploded perspective view, and FIG. 4 is an explanatory view showing a phase angle of the cancel cam with respect to the fitting pin. A turning center shaft 3 is provided on a base 2 of the turning indicator of the vehicular turning indicator 1 at a position deviated from the center to the right and displaced by an angle θ in the counterclockwise direction.

A bracket 4 is rotatably supported on the rotation center shaft 3. A turn signal operation lever 5 is attached to the bracket 4 and projects to the right of the base 2. Holding arm 6 and tip 7 of bracket 4
The ratchet 8 is held by. A moderation ball 10 biased by a moderation spring (not shown) protrudes from the cylindrical part 9 of the tip part 7, and the moderation balls 11 formed on the base 2 correspond to the neutral position and the left and right direction indicating positions. It is adapted to engage the valley 12 to hold the bracket 4 in that position.

A cancel cam cylinder 14 is rotatably fitted to the outer periphery of a cylinder portion 13 provided at the center of the base 2. As shown in FIG. 2, in the cancel cam cylinder 14, a flange 16 is formed at the lower end of the cylindrical portion 15, and a pair of fitting pins 18 opposed to each other in the radial direction are fitted to the upper surface 17 to the lower surface of the steering wheel. Has been made to do. An axial fitting guide 19 is formed on the outer periphery of the tubular portion 15 for each equal angle θ so that the phase angle with respect to the fitting pin 18 is a multiple of the angle θ. Into the fitting guide 19, a cancel cam 20 having a fitting groove 21 that fits in a male and female relationship is fitted.

The cancel cam 20 is engaged with the ratchet 8 held by the bracket 4 rotated to either the left or right direction indicating position when the cancel cam cylinder 14 is rotated in the cancel direction by the steering wheel. ,
The bracket 4 is returned to the neutral position. The phase angle θ between the fitting pin 18 and the cancel cam 20 is
As shown in FIG. 1, the rotation center shaft 3 with respect to the center of the tubular portion 13
Is determined by the position of. Therefore, when the position of the rotation center shaft 3 is changed in order to ensure the visibility of the mark attached to the turn signal operation lever or the instrument panel instrument according to the difference in specifications in the same vehicle type. To cope with this, the cancel cam 21 is refitted to change its position. Therefore, there is no need to design a new cancel cam cylinder.

FIG. 3 shows another embodiment of the cancel cam cylinder. A pair of cancel cams 33 facing each other in the radial direction are formed on the outer circumference of the cylindrical portion 32 of the cancel cam cylinder 31. And the flange 3 on the upper end
4 are formed, and a plurality of fitting holes 35 are formed on the upper surface thereof at equal angular intervals θ in the circumferential direction. A plurality of fitting pins 37 that are fitted into any of the fitting holes 35 are formed from the lower surface of the ring body 36, and a pair of fitting pins 38 facing each other in the radial direction are formed on the upper surface of the steering wheel. It is formed to fit on the lower surface. Therefore, the cancel cam cylinder 3
By changing the fitting position of the fitting pin 37 of the ring body 36 into the first fitting hole 35, the phase angle θ of the cancel cam 33 with respect to the fitting pin 38 can be changed. Therefore, even if the position of the rotation center shaft 3 of the bracket 4 is changed, it is not necessary to design a new cancel cam cylinder.
