Problems solved by technology

[0009] However, in the above-mentioned conventional example, since the press-fitting ribs are arranged on the same circumference around the ignition switch, it is impossible to completely prevent the rotation toward the fitting direction using the crimping part as a fulcrum, so there is a problem that the rattle prevention effect is insufficient. shortcoming

Embodiment Construction

[0031] figure 1 An embodiment of the present invention configured as a steering lock device is shown. The steering lock device has: a housing 2 into which a plug 1 can be inserted, and the plug 1 can only be rotated by a unique unlock key; and an ignition switch 3 connected to the housing 2 .

[0032] In addition, a locking body is attached to the housing 2, and the locking body advances and retreats relative to the housing 2 as the plug 1 is rotated. When the plug 1 is at the locked rotation position, the locking body is engaged with an unillustrated steering shaft. , and lock the steering shaft.

[0033] Such as figure 2 As shown, the ignition switch 3 is formed by accommodating an unillustrated switch board and a circuit board on which terminals are arranged in a cylindrical main body portion 3a, and can be changed by rotating a rotating shaft 3b fixed to the circuit board. The state of connection between contacts on a circuit board. It should be noted that, in figur...

Abstract

An object of the present invention is to provide an engine starting device which can prevent rattling of an ignition switch in a coupled state. Provided is an engine starting device including: a housing 2 accommodating a rotational operation shaft 1; and an ignition switch 3 coupled to the housing 2 and configured to be actuated upon application of rotational operation force to the rotational operation shaft 1. The ignition switch 3 is fitted and held in an attachment recess 4 formed in the housing 2, in such a way as to be prevented from falling from the attachment recess 4 by appropriate snap-locking portion 5. The peripheral wall surfaces of the ignition switch 3 and the attachment recess 4 on the fitting start end side and the peripheral wall surfaces thereof on the fitting finish end side come into pressure contact with each other substantially simultaneously with each other when the depth of the fitting of the ignition switch 3 to the attachment recess 4 reaches a predetermined depth, to thereby reduce rattling in the radial direction.

Description

technical field [0001] The present invention relates to engine starting devices. Background technique [0002] An engine starting device described in Patent Document 1 is known as an engine starting device used in a vehicle. In this conventional example, the engine starting device is formed by connecting an ignition switch to a housing that accommodates a camshaft (rotary operation shaft). [0003] For the connection of the ignition switch, the ignition switch is embedded and held in the switch installation part formed at the rear end of the housing, and the elastic piece is elastically locked to the engaging part of the housing to prevent the ignition switch from falling off. [0004] In addition, a press-fit rib is provided on the ignition switch, and the press-fit rib presses against the side edge of the opening opened on the side wall of the switch mounting part to limit the rattling of the ignition switch after it is inserted.
