TECHNICAL FIELD

The present invention relates to a shock absorber which absorbs shock.

BACKGROUND ART

PTL 1 and 2 disclose a stroke sensor system including a movement amount deriving unit which obtains a movement amount when a cylinder and a rod inserted into the cylinder move relatively. In the stroke sensor system, a protective member (guide) is provided to protect the rod and a coil for obtaining the movement amount is provided inside the protective member.PTL 1: JP-A-2016-165984PTL 2: JP-A-2016-166845

SUMMARY OF INVENTION

In the inventions described in PTL 1 and 2, the protective member is arranged at a position where the protective member receives a load of a suspension spring. When the inventors of the invention actually manufactured and tested a shock absorber having the same structure as the inventions of PTL1 and 2, from the viewpoint of increasing the durability of the coil in the protective member, it has been found that it is preferable to prevent the load of the suspension spring from being applied to the protective member.

An object of the invention is to provide a shock absorber which can protect a protective member with a coil from a load of a suspension spring.

According to an aspect of the invention, there is provided a shock absorber which includes a cylinder which is a conductor, a rod inserted into the cylinder from one end side of the cylinder, a suspension spring arranged outside the cylinder, a spring receiver which receives a load of the suspension spring on the one end side of the rod, and a protective member arranged on the one end side of the rod and configured to protect the rod. The protective member has a coil configured to detect a relative position between the cylinder and the protective member, and an end portion formed on the one end side of the protective member is arranged so as not to receive a load from the spring receiver.

According to the aspect of the invention, the protective member having the coil can be protected from the load of the suspension spring.
